I'll second the Mutant League games. I loved Football but never was able to get a hold of a copy of Hockey to try.

I loved playaction football I would rush for 1500 yards with the option play

I would always play as the Niners and onside kick the ball. Once you learned the trick, you could always onside to the left side of the field and switch to Ronnie Lott and scoop it up. I would always destroy the computer. With buddies it was tougher to get them that way.

The Giants were great in Play Action Football, but they didn't have a player as dominant as Mutant League's Bones Jackson.

I like the was you think!

Mutant league yeah those were great games

Good call. I still get out the Dreamcast just to play these two and would gladly pay $16 for the pair.
