Here Comes The Pain. The Roster was so stacked at that time and you can tell a lot of care and time went in to that game. But I have to admit I do prefer the new control set up; using the joystick to grapple seems more natural to me. With that said I still like the over all look and feel with Here Comes The Pain.
For me it was smackdown 2 on ps1 as that was the game i played for years as i was too young to get myself a ps2 at the time other wrestling games i loved for multiplayer were WCW vs nWo: World Tour and WCW/nWo Revenge.
It was a pitty i missed out on WWE no mercy.
For most current it has to be Here Comes The Pain after that i just felt dissapointed as they all feel the same each year.
