another fun one if you're in an exotic situation and don't have a framebuffer (or if you just want to have some fun by making your games to look worse):

export SDL_VIDEODRIVER=aalib

unfortunately it's only SDL1, though

export SDL_VIDEODRIVER=caca is more usable for games

[antisol]

Oh nice! How did I not know it works with caca?!

Works pretty well even. I wish there was a libchafa variant, and ideally for SDL2.

I've even played SC2, The Ur-Quan masters fairly successfully in an ssh session that way. And Frozen Bubble.
