the whole 32x lineup is boarderline on this topic; some games are just mediocre but I find it to still be pretty fun. With 36 games released I could easily run thru the entire lineup right here but I'll just post a few
Afterburner is good but I honestly don't remember any difference between this version and any of the other sega releases. Good pick up if you dont have any of the other ones or are a fan of the series.
Blackthorne people seem to like but I hated the controls. Good visuals in the levels so I'll give this one another go eventually haha
Cosmic Carnage playable robot fighter
Decent Doom port (prolly second best console version, Jaguar has #1)
Kolibri is a must own. Beautiful horizonal shooter, based on nature (you're a hummingbird). Excellent visuals
Knuckles Chaotix you'll either love it or hate it. Doesn't seem to be much middle ground here
Spiderman Web of Fire is definitely not worth the price tag. Stay away unless you find it at a cheap price (under $50 cart only, ~$100 complete) and I'm just suggesting that for re-sell.
T-Mek is a good robot/tank simulation game (like mechwarrior? if I remember correctly)
Tempo is worth it just for the 90's rap intro
Virtua Fighter is Virtua Fighter. Cant go wrong there.
Zaxxon is a pretty fun, isometric shooter
all the CD FMV games are so bad they are good. Any of the 32x video upgrade is minimal at best (I havent even noticed any).
I love the rasta guy in Corpse Killer. I dont have the bazooka gun they made for the genny but I bet that game is a blast with it.
Havent got past the intro movie to Supreme Warrior but that part warrants a playthru
Scotty Pippin Slam City is ridiculous, 4 cds (1 per each opponent) you press a button while youre on the court and you watch a basketball move
