I think they are talking about the PSO game, not the original game.
The over all, usage of the "Xenogears" world is what is troubling. So far they had three lame boring robot RPG games, that puts you to sleep. Along with strategy war games. However that is what it looks like.
I am pretty sure, all they need is the mechs ( the robot suits ) from the previous games.
I really wish Star Ocean would have an MMORPG, that was built up, like the original SNES game, but feature things from the Blue Sphere and EX series.
XenoGears is alien to everybody, so nobody has anything against it. The story is random sci-fi blah blah Star Treck rubbish, and you can't even take anything seriously.
