I have never found the Gex series to be "exciting," even when it was new. Gex was always a shallow also-ran mascot in the time when everyone was trying to recapture that lightning in a bottle without understanding how it actually worked, and desperately trying to recreate what Sonic and Earthworm Jim and to a lesser extent Toejam and Earl had.
He was marginally less annoying than Bubsy. That's about all I can say about Gex.
If I really decide to play some sub-par 90's platforming stuffed with stilted and dated TV and movie references, my 3DO still works. Yes, really...
