I play games like Risk, Battleship, and Puzzle with your Friends on Steam with him, but I’m looking for more options that are simple enough for him to learn (especially since there’s a Steam sale on now). Bonus points if it is co-op for me to play with him.
Ideal game: not much/no reading, easy to learn, possibly world war 2-themed, ideally mouse-only, and turn-based instead of real-time
Zachtronics has a lot of puzzle games, ahough some are VERY obtuse there are some very simple ones that your father may enjoy, my personal recommendation is Opus Magnum, i think he may enjoy It
