Dead Cells, Vampire Survivor, Loop Hero, Devil Daggers/Hyper Demon (more m+k games though), FTL, Into the Breach, Shovel Knight, VA11HAllA (or whatever, the cyberpunk bartender one), really any rogue like...

Great time to buy. Probably won't be cheaper between now and DLC launch. There's already been tons of changes to balance and the class system, performance has significantly improved. It's honestly just a really wonderful world and role playing experience. I also highly recommend the short anime if that's your sort of thing.
