The best platform games nobody cares about but you
I don't want to see this thread turn into some "wai wai 2D forever 3D games have no soul ^______^" f*****-c*** festival, but I'm as bored as shit. I got kicked out of my dorm for a week for spring break, I'm holed up in my friend's filthy pad, and all I've got to keep me busy is the Complete Hitchhiker's Guide, a yo-yo, and my laptop. Fortunately for me I left my Playstation->USB converter and a controller in the bottom of my backpack from god knows when, and I'm in the mood for some games.
So, I come to you for advice. I'm looking for the best platform and/or action games from the 16 bit consoles or earlier I've never played. I've seen a couple that looked interesting in other threads that I'm going to seek out try. Mr. Gimmick, Magical Troll Adventure (or whatever the hell, I remember seeing it in Die Hard ads, I think), and whatever the SFC Milon's Secret Castle sequel was called. Doesn't need to be too obscure, just the stuff most people probably overlook. I can have fun playing Actraiser or Super Mario World or something, but I've already done it a hundred times over. I'm looking for something different that I've probably missed.
Feel free to list your favorites. Or don't, that's alright too.
