Well to my knowledge the last game availlable with the late Eddie Gurerro, has Cena, Undertaker and the usual big names as well the smaller names (hidden characters avail). Several types of matches from Royal Rumble, Tag, Tournament, Casket, Weapons.
The create-a-wrestler mode has improved since previous releases, This is where the graphics show there flare, as normal casting methods on the programming for superstars has always been set to ratio's within fps, this release differs in the ratio's of any other wwf/wwc/wwe game, especially by THQ.
Now overall this game has better storyline and more realism than before, also that since every character has individual outcomes based on your decisions made in Tournament, you will have hours of play, infact days, months.
I will give more out overtime when i progress in the game myself, but i can not confirm nor confirm the possibility of Bret Hart being a playable character, some rumours say he's available but not in Tournament mode.
I base this on the PAL (Region4 std. Countries).
P.s im not sure if anyone else has done a review on this game yet as search feature wasnt working.
