The level of quality that Level 5 put into their RPG's is staggering. You'll be hard to find a game that is more worth your money than a game from Level 5. Rogue Galaxy is a perfect example on how much depth and detail Level 5 put into their games. Its hard to gripe about anything in Rogue Galaxy as it is all played out flawlessly, you'll only dislike the game if what there offering you is not your thing to begin with.

I have yet to play Odin Sphere. Im sure that game is great and all but no other game developer knows how to push my buttons as much as Level 5 do. So my personal opinion is that Rogue Galaxy is the better game.
