Typically one main competitive multiplayer game interspersed with play on more casual games that sit well (ex. Stardew Valley) or games that lend themselves to one-off casual MP play (ex. Rocket League). On urges I tend to throw in emulated play of old classics from the "must experience" heap that never dies, or try out more casual mobile games that aren't lame (ex. Reigns, Words with Friends, chess puzzle apps, etc).
As I've gotten older it's gotten tougher and tougher to get into the more hardcore, dedicated SP narrative-rich games at the same time I'm playing something that requires 2+ hrs/day practice just not to get run over by all the kids with their goddamn fresh-as-a-baby reaction times and decision-making processes. It's ironic because all those years on the blacktops when I was younger I never once thought that video games were something where it would similarly be appropriate to stop and think, "Okay, remind yourself to enjoy this, because it won't last, and all the straight-shooting curmudgeons have told you how much that is going to suck."
