Ace Online
A free-to-play aerial MMOG with persistent nation wars.
Ace Online, also known as AirRivals and formerly Space Cowboy Online, is a free-to-play 3D shooter MMOG from MasangSoft Inc., owned by YD Online Corp. Players pilot customizable starfighters called Gears across terrestrial, lunar, and space maps. The game features typical MMORPG elements like leveling, currency, and skills, but combat is heavily player-versus-player (PvP) oriented. Progression comes from fighting non-player characters and completing missions, which unlock new maps. No player is ever invincible in PvP, regardless of level. Players can trade items, customize Gears, form parties (formations) and guilds (brigades), and engage in aerial combat from a third-person view, with an optional first-person cockpit view. When creating an account, players choose a fighter with a distinct play style.
The game’s item shop, available since the game's launch on May 26, 2006, lets players buy items with currency purchased through an Ace Online account. These items can temporarily alter weapon effects, stats, or experience rates. The shop also offers services like Weapon Gamble, which randomly enchants weapons with prefixes and suffixes, and Enhancements that boost weapon and armor performance. Only five enchantments can be applied safely; the sixth attempt risks breaking the equipment.
Ace Online’s persistent Nation War system pits two nations—Bygeniou City United (BCU) and Arlington National Influence (ANI)—against each other. National Contribution Points (NCP) are earned by shooting down enemy Gears, as well as through Strategic Points, Mothership wars, and Arena battles. Raids involve constant battles over maps that offer strategic and economic advantages, such as access to the boss monster Pathos in BCU’s Zaylope Beach. Controlling a map allows a nation to destroy Pathos for rare drops. Skirmishes are unorganized battles on neutral maps, often sparked by a single intruder, and are a major source of fame and NCP. The neutral zone Bark City is a popular skirmish site due to its open spaces, repair shop, and access to four areas.
The game launched in North America as Space Cowboy Online on May 26, 2006, via gPotato (operated by Gala-Net), after its client became available on May 22. It shut down on December 26, 2007, announced by Gala-Net staff.

Lore & Background
Ace Online began as Space Cowboy Online in North America, hosted by Gala-Net through the gPotato portal. The client was made available for download on May 22, 2006, and service went live on May 26, 2006. On December 26, 2007, Space Cowboy Online was shut down, announced by Gala-Net staff. Following this closure, the European version was hosted by GameForge GmbH and renamed AirRivals in early 2008 (originally intended to be called Flysis). The North American release resumed under Suba Games on September 26, 2008, as Ace Online. Other publishers followed: Arario Corporation launched the Japanese server in the first quarter of 2009, and Axeso5 opened the first Latin American server in February 2011.
Reader's Guide
Ace Online's significance lies in its long-running, player-driven nation war system, which has sustained the game across multiple publishers and regions for over a decade. The core gameplay involves piloting customizable starfighters (Gears) in aerial combat from a third-person view, with an optional first-person cockpit view. The Nation War system pits two factions—Bygeniou City United (BCU) and Arlington National Influence (ANI)—against each other in raids, skirmishes, and mothership wars. Motherships, such as BCU's Anubis and ANI's Horus, spawn when a nation accumulates enough National Contribution Points (NCP), and their destruction grants bonuses like increased recovery rates and access to exclusive maps. Strategic Points and arena battles also contribute to NCP and War Points, which can be spent in the War Point Shop. The game's free-to-play model includes an item shop (available from June 23, 2006) offering enhancements, weapon gambling, and enchantments, with a risk of breaking equipment beyond the fifth enchantment. The legacy of Ace Online is that of a niche but persistent MMO that maintained a loyal community through its structured PvP and territorial control mechanics.

The Dawn of Playable Virtual Spaces
In the mid-1970s, a handful of experimental programs quietly laid the groundwork for every multiplayer world that would follow. In 1974, Mazewar gave players a first-person view of a maze where they could shoot one another, making it both the first graphic virtual environment and the first truly networked game. Its creators initially linked machines with a simple serial cable, but once one of them enrolled at MIT, the title was upgraded to run across ARPAnet, the embryonic backbone of today's Internet. The following year, Will Crowther built Adventure on a DEC PDP-10, creating the first widely played text-based dungeon crawler. Don Woods expanded it in 1976, weaving in Dungeons & Dragons-style elements and even a computer-controlled dungeon master. That success inspired a team of MIT students to write Zork in the summer of 1977, which quickly became a hit on the ARPANET. A DEC programmer then ported it to FORTRAN under the name Dungeon in 1978, ensuring the concept reached an even wider audience of early computer enthusiasts.
MUDs and the Cultural Explosion of Text Worlds
Roy Trubshaw, a student at Essex University in the United Kingdom, began coding a multi-user adventure in MACRO-10 assembly language in 1978. He named it MUD in tribute to the Dungeon port of Zork he had enjoyed playing. After converting the code to BCPL, the precursor of C, he passed the project to fellow student Richard Bartle in 1980. The game, later remembered as Essex MUD or MUD1, kept running on the university's network until late 1987. Its influence surged across the Atlantic during the 1980s, when inexpensive personal computers and 300-to-2400-baud modems let college students dial into multi-line bulletin boards and services like CompuServe. The community jokingly reinterpreted the acronym as "Multi Undergraduate Destroyer" because of how much time students poured in. In 1989, Yehuda Simmons released Avalon: The Legend Lives, introducing a deep economic system, player-elected governments with ministers and barons, a layered warfare conquest system, and a meritocratic player-versus-player structure based on skill-worth rather than levels. Many designers who would later shape the MMORPG genre, including Raph Koster, Brad McQuaid, Matt Firor, Mark Jacobs, Brian Green, and J. Todd Coleman, cut their teeth as MUD players or developers.
PLATO: Graphical Multiplayer Before It Was Mainstream
While text-based adventures dominated the public imagination, the PLATO educational system was quietly pushing graphical multiplayer design years ahead of the curve. By mid-1974, PLATO hosted Spasim, a space-battle game accommodating up to 32 simultaneous users, alongside Talkomatic, a multi-user chat system. Oubliette, written by Jim Schwaiger, predated MUD1 by roughly a year and was so punishing that no single player could survive alone; groups were mandatory. Moria, copyrighted in 1978, followed with party-based gameplay that also allowed solo character management. Perhaps most remarkable was Avatar, begun around 1977 and opened in 1979 by three high school students—Bruce Maggs, Andrew Shapira, and Dave Sides—using PLATO at the University of Illinois. Running on 512-by-512 plasma panels, this 2.5-D dungeon crawler let groups of up to 15 players team up to fight monsters simultaneously. Despite their sophistication, these titles were locked inside PLATO's proprietary infrastructure and could never reach the broader public. Textual worlds running on Unix, VMS, or DOS, by contrast, were far more accessible, which is why they shaped the next generation of multiplayer design.
The First Commercial Online Worlds
The leap from academic experiments to paid consumer services came in the mid-1980s. Island of Kesmai, designed by Kelton Flinn and John Taylor, is generally regarded as the first commercial MMORPG. This roguelike title launched in 1985 on CompuServe, charging players twelve dollars per hour and supporting up to a hundred simultaneous users. Around the same time, in early 1985, Games Computers Play (GCP) opened as a dial-in service for Atari 8-bit computers out of York, Pennsylvania. Users connected via 300- or 1200-baud modems and navigated an isometric virtual mallscape with a joystick, chatting in private or group rooms, exchanging mail, and entering different doors to play multiplayer games. Though Commodore's PlayNET edged out GCP by a few months as the first graphical online service, GCP's lineup included Lords of Space, widely cited as the first commercial graphical MMO. Together, these early paid services proved that multiplayer virtual worlds could sustain a business model, setting the stage for the massive online titles that would follow in the decades ahead.
