In the past I'd say hardcore multiplayer. I was very interested in games like Ark, Rust, and anything else with some semblance of PvP. I'm actually pretty disappointed that the PUBG era has come about right after the birth of my first child which goes without saying has killed most of my ability to game.

As I mentioned above I just recently became a father so my gaming has moved from multiplayer to single player rather quickly. Not that I mind single player but there is a huge lack of great single player games coming out. I've been taking the time I have to visit old games that I haven't played yet and just started with the witcher series. So Hardcore PvP not to Single Player story driven.
