The Witcher 3 is probably overall the best of the games, if you don't like it I don't think you'd like W1
Ghostrunner is on sale, or at least was, on GOG so try it out to see if you like it.
GOG has like a 30 day refund policy or something similar, IDK I've never used the refund thing.
Plus, on lutris's site you have a ton of install scripts for games so you can just check out whats free and start playing with like 4 mouseclicks.
