For me there is only one winner in terms of WWE computer games and that's this beauty right here...
The career mode on this bad boy was immense and the general gameplay and graphics best of it's time. The create-a-wrestler mode was pretty sweet and challenging for belts in exhibitions made it all the more interesting between friends.
The last version - WWE13 - had an Attitude Era mode where you played out famous moments like Austin/Mcmahon etc... I only rented it so never gave it a proper go but it felt like a vast improvement on the earlier Raw Vs Smackdown games.
It has Universe mode, which is pretty much GM mode. You basically can pick and choose what happens for the most part and they have random cut scenes and storylines and what not to add. Its a good time killer.
