Rock 'Em Sock 'Em Robots Arena was pretty good. A robot fighting game where you could focus damage onto specific parts of your opponent to knock them off. Not only would they be unable to use that part in that match, but then you’d have the option of swapping out your own parts between matches in the tournament mode.

I’m not particularly fond of fighting games, but the gimmick really drew me in to this one. I remember a lot of fights where I had to choose whether to prioritize just plain winning vs trying to get a specific part for a build.
