I think Tiberian Sun and Red Alert 2 aren’t 3D graphics games though, they’re both ‘isometric’ games, so they use 2D graphics to give a slight illusion of 3D-ness and so SDL is perfect for that.
I’m working on an isometric game myself at the moment, see https://www.youtube.com/watch?v=IYyC472tqbY and I’ll be using SDL when I port it to Android and Windows - as I do with all my games!
