By the time I get to playing a series usually several games in that series have come out. I usually play games that are 5+ years old, I don’t have time to keep up with current releases and that’s more expensive anyway. Playing on a multi-year delay keeps me away from over-hype of game releases and by the time I play them they’re patched, have all dlc, whatever else is applicable. I don’t do it for every game obviously but it’s my typical way of buying games
