I'm building a MAME machine, custom UI, it really only works with about 50 games.  Anything above that and it's unwieldy.  Anyway, if you could only have 50 games what would you put on it, assuming this game was yours.

This has twin fighting sticks, trackball, spinner, and light gun.

Let me know what you would really want in your game list.

X-Men
The Simpsons
Every TMNT game

Other random action games:
The Punisher + Nick Fury (spent half of a trip to Disney world in the hotel arcade playing it rather than at the park)
