If you like RPGs, try to track down a copy of Grandia 2.
It's a fairly poor DC conversion (slowdown shows up quite often), but it's still got the best combat system I've ever seen.
Also, if you're a fan, it's worth giving Spider-man 2 a go (maybe a rental), the missions are fairly repetetive and uninspired, but the web-swinging is done brilliantly, there really nothing else like it. Hardly a great game, but you can probably find it cheap.
