@dictatordave @Rasterman it's been a very long time since I've played any SNES games, TBH, so let me see if my memory doesn't fail me.
Besides the very common "best SNES games" that you'll find in every top 10 list, I really enjoy:
Kirby's Dream Course - Basically Kirby golf
Biker Mice from Mars - Plays almost like Rock'n Roll Racing, but you can't change cars, each "car" is a character from the cartoon series with it's own movement and weapons, really fun
Ardy Lightfoot - It's a surprisingly good platformer game
Maui Mallard in Cold Shadow - Anoher very good platformer
Doom Troopers - Run and gun platformer kinda like Contra, with lots of gore and cool ways to kill enemies, which is insane for a SNES game
EVO - Search for Eden - It's a platformer game where you start as a fish and keeps evolving, you can choose your mutations and get a few branching paths. Pretty deep for a SNES game.
Tales of Phantasia - You'll need to find a translation romhack because this one is Japan-only, but it is IMO the best JRPG on the SNES (yes, better than FF6 and Chrono Trigger).
@RegalBeagle @dictatordave @Suzu I saw this one before and have it on wishlist.
