No Mercy for Nintendo 64..
It had everything the first three AKI Nintendo 64 Wrestling Games had, plus more features like Ladder Matches..
Also, Smackdown vs Raw 2006 on PS2 is pretty sweet. Probably the first wrestling game in quite a while that I've actually enjoyed.
Smackdown 2 on the PS1 was cool just because of the 2 Player Career mode that I can't remember any other wrestling game having...
WWF Warzone, Attitude, and the ECW Games used the same engine and they were terrible... The two EA-made WCW games were terrible, Backstage Assault and Mayhem, I think they were called..
And the early THQ Wrestling Games were pretty terrible..
WCW Nitro
WCW Thunder
WCW vs. the World
Wrestling Games became good on teh Nintendo 64, and since then, haven't been quite as good, yet.
The Fire Pro Game I had for Game Boy Advance is actually pretty cool. It's 2D, but it's definitely the best 2D wrestling game I've ever played.
