Cyberpunk 2077 was probably my biggest patient gamers win... I usually practice just to wait for a sale because my backlog is big enough already, but giving this one time to cook, drop the dlc, and then go on a steep sale? I think I got it for like $20 USD and it got close to 500 hours in it by now...

Runner up would be No Man's Sky...another one that just keeps getting better the longer you wait. Only downside is they keep announcing new stuff...so it's almost like they keep resetting the clock.
