I pretty much exclusively play solo lobbies in GTA Online, Fallout 4 Survival Mode with a bunch of mods, or Elite Dangerous. I grabbed LittleBigPlanet 1 and 2 for RPCS3 recently too because I find those games fun to play through occasionally. Turning 31 this year. At least half of my game time I end up putting into development of my own amateur dev project (webm related) because I find development and level design to be fun similar to just playing a game. I do have short periods of existential dread where video games and development seem completely pointless but after a refresh I always end up playing or doing something.
