Here we go:
5. Mutant Melee (PC). Never completely beat it, but I had a lot of fun...and frustration...playing it. Loved that you could play as a lowly Foot Ninja.
4. Fall of the Foot Clan (GB). The only TMNT game I owned as a kid (though friends had others, and I'd rented others) it has a nostalgic value to it. Way too easy to be higher on the list.
3. Tournament Fighters (SNES). TMNT meets Street Fighter II, what more could you want?
2. TMNT Arcade. When I was a kid, the Chucky Cheese's had the 4 player cabinet. So if ever a friend had a birthday party there, me and three of my buddies would pop tokens in that puppy 'till there was no tomorrow. Luckily my friends all liked different Turtles, I didn't have to fight for Raph (But who would...his control placement sucks.)
1. Turtles in Time (SNES). It's the best beat-um-up of all time depending on who you ask, and the SNES port actually improves on the stellar arcade game with added staged and special attacks.
