GEX was a fun game and character honestly. It was an interesting idea having the character spout off one liners randomly or seemingly anyhow. The levels, if I recall had invisible trigger points that only activated on a set timer when you passed them. But the one liners kind of killed the game now.
(Also they do get FUCKING Annoying after the umpteenth time you hear them in one level)
It's very dated. Most new players wouldn't get them, and some would be outright offended by them. Take the Chinese level from Enter the Gecko. GEX made a lot of let's say, very 70s Kung-fu movie references in a stereotypical Asian voice, if you know what I mean.
I like the game even to this day but man, they did not age well. Also, GEX is probably the only good thing Dana Gould has ever done.
