My pet peeve: matchmaking in games vs dedicated servers. Yes, dedicated servers had problems, and required some technical know-how to run as well as decent hardware. But they were mini communities. And some people actually enjoy matches with some level of imbalance. Mopping up a few players, getting smashed when you stumble upon a great one. There were some to watch out for.

Long story short these days I play single player games and board games. As a bonus, a well thought out board game stays relevant forever. It never has its servers disabled or becomes incompatible with new system.
