Ok, now that I've been playing No Mercy for N64 for about a month now, I can say it is the best wrestling game I have played. I found some websites that tell you how to make all of the new wrestlers and update the existing. I still need to figure out how to do some moves, but I'm getting better.
Some of the challanges in the career mode are hard, but that's what makes it fun. I haven't played all of the match types yet because I've been doing the Survival mode to earn cash and the Career mode to unlock a few more wrestlers. I have yet to do a ladder match and a table match.
