Civ 5 here. I'll be 39 this year and play the least out of my friends group (probably 1 or 2 sessions a month where I quit 3 or 4 hours in, and once a month or less playing for 6 or more hours to almost actually finish a game). The friends I play with are all mid 40s and do a full game at least weekly. We all have wives and kids and stuff but are huge nerds i guess.
I have launched Civ 6 once, launched a quick game with bots, blinked and realized 2.5 hours have passed. I'm scared to reopen the game. Next time I might wake up with a gray head and wrinkles on my face
