I haven't kept up with any wrestling games after WWF No Mercy for the N64, that game is kickass though, unfortunately I can't find the memory card required to save any of my current progress so i can't unlock new stuff.
And yes there actually were N64 games that required memory cards, wtf.
I always hear that the physics haven't been updated enough to warrant all the sequels, or that THQ don't take enough time to develop every game fully because they just dish them out every year. That seems to be a trend with sports games.
They need to make another "Legends" game and do it right, I don't care about these new jabronis. Give me Bret Hart, The Hulkster and Andre.
