DoomRL, the roguelike based on the DooM setting has had a recent graphical overhaul with sprites added instead of text characters. (You can play it with the new tileset graphics or play with using the older traditional text graphics.)
I'm having a lot of fun with it but I'm having trouble surviving past a 6th floor on Hurt me Plenty. It sorts of plays off as turn based survival horror as long as you don't have any vision enhancing perks. Try it, it is free!
