Why you might like it
- A comic-book-styled fantasy MMORPG notable for a distinctive 'siege dungeon' system where guilds fought over ongoing control of valuable dungeon prizes, adding real territorial-conquest stakes to standard PvE content.
- Had genuine international reach across multiple regional versions (Japan, Korea, and others) beyond its US gPotato release, with a later community-run 'Battle Dungeon' server built on the Japanese version's more developed features.
- Worth knowing about for fans of mid-2000s comic-styled fantasy MMORPGs researching this specific gPotato-published title.
Things to consider
- The US/gPotato service is confirmed permanently closed — publisher NDoors terminated it on March 5, 2010, with all player data removed and no transfer path offered to other regional versions of the game.
- Community coverage from 2013 mentions the Japanese version was also shut down at some point, with only unofficial fan-run servers (like 'Battle Dungeon') continuing informally — treat any such server as unofficial and unverified rather than a stable, supported service.
- As a mid-2000s MMORPG, expect its combat and interface conventions (point-and-click movement, Diablo-style fighting) to feel dated by modern standards.
