Its hard to decide... I'm probably going to go for Versus just because between the two, I feel Versus will be almost exactly what you think it will be. The kinda game you know exactly what to expect when you play it. I sorta see it as DMC meets AC with the KH2 battle system. Plot I'm not so sure about but since very little has been said I can't comment on it. I just hope that A.) Its a one shot story. B.) Its fleshed out.

XIII is sorta've in a "wild card" zone for me but then again the more abundant (and yet not enough) information on it makes it a little more troublesome for me. XIII has a few good elements (story sounds intriguing and original, combat system has potential to be awsome) and then some not so desirable elements (looks like a compilation of elements from VII, VIII and X, mecha shiva! I can't wait to "ride" her! This teams last project together was X and X-2!). Basically I can see it going either way. My problem is that this team can come up with some cool and original ideas but they just can't seem to use and execute them as well as I would like. Basically I won't get my hopes up cause this team has let me down before.

My vote, I guess goes to Versus but only due to a total lack of info... Though I've heard Versus is suppose to be based on the Epic of Gilgamesh...
