At the mall today I ran across an old game I hadn't seen in ages; Space Station Silicon Valley! I bought, and I'm glad I did. It's lots of fun, just like I remembered it being. The premise is, you're in an outer space amusement park, full of animal-robot hybrids, and you, a computer chip, have to kill and take over the bodies of these animals in order to solve puzzles, get to new areas, etc. For the N64, it's a super innovative game, and there has yet to be another game like it! Here's a link for anyone who's curious.
