Sega, Capcom and Namco are hard at work creating a new Strategy RPG together called Project X Zone. So far there are not that many details about the game, but what we do know is that the title will be featuring popular characters from all three companies. It is also quite likely that these characters will be adventuring and battling with and maybe even against each other.
According to sources (dothackers.com and famitsu) the game is going to be appearing on the 3DS in Japan at a later date. Much like the Super Robot Wars series of games, it looks unlikely that the game will be released overseas due to licensing issues, but if the companies can work together in Japan, I don’t see why they can’t over here.
