Until we get a multiple (full-length) stories that branch depending on choices, nothing will ever be a No Mercy killer. And seriously, NM AI can kick my butt 15 years later so yea, that's good.
Yeah! Those branching stories like:
You Beat Crash Holly! Now Here's a Handicap Match with Crash Holly and Hardcore Holly!
You Lost to Crash Holly! Now Here's a Handicap Match against Crash Holly and Hardcore Holly!
and let's not forget:
YOU WON THE ROYAL RUMBLE! Not really, you were disqualified for something that never happened but we told you happened to progress the story down the same path as...
YOU LOST THE ROYAL RUMBLE! Now you have to complete a bunch of timed matches, handicap hardcore matches, and fight ramped AI to continue the story!
QFT, No Mercy was probably one of the greatest games of its time alongside the first 2 smackdowns and the other THQ/AKI wrestling games, but I'd honestly rather play Shut Your Mouth or Here Comes The Pain's story modes, they are WAY better than No Mercy's.
