I played the X-Men arcade recently in arcade form set on freeplay. I do plan on getting it because I love it, but a word of warning however. It's insanely easy on freeplay. When you use your mutant power, it takes a hit on your health, but clears the whole screen of enemies most of the time. When there's no risk in dying because you can simply continue where you stand, simply spamming the mutant power will coast you through the game with zero effort. This is simpler than Gauntlet on XBLA. If you go in playing "legit" and trying to stay alive as long as possible, like it's costing you .25 a pop, then that's one thing, but there's no consequence in dying now. Like I said, I'll get it out of nostalgia, but this is one of those games to pick up, play once or twice, then probably get shelved for a year again if you don't have many friends to play with.
