Just for the record I don't think Tron sucks LE or pro, doesn't matter, they both play so similar it almost doesn't pay to even say they are different, unless your buying or selling. Gameplay wise, they are very very similar. Not a drastic change like TF or AC/DC is from the premiums to the pros. Drops or standups, changes it a little bit. but that's about the extent of it.
Tron doesn't suck, and if I have room for 30+ games, the wife might talk me into getting one someday. But if i'm talked into it, i'm getting a pro, because the little bit of stuff the LE has, isn't worth 6k to me at all. In fact, I don't think i'd even pay 2k over a pro for what it has. Yes it looks nice and everything, but that little arcade mod, is better than anything on there from the factory. LE or not. that arcade mod is one of the best mods i've ever seen and that would be the whole reason I would even consider getting one. (besides the fact that the wife loves Tron and would really want me to get one) But she also loves Star Trek, and i'd much rather have that game.
