Atlus has been known to be a respected localization company for Japanese games. They have recently expanded into the MMO market with the launch of NeoSteam. This may be a move on Atlus' part to expand its MMORPG library after its first MMO launch of NeoSteam in North America.
Gonso Rosso has been struggling from financial strains, which questions how great these new Japanese MMOs really are. Under their belt they have published Pandora Saga, Arcadia Saga, Tower of Druaga, Shaiya, Via Rosso, Ran Online and Master of Epic.
Even if Atlus has acquired a majority in GS it is still speculation of if any of the MMORPGs will be coming over to Western territories, but at the same time it is likely we may see at least some of the games.
