It depends. It’s fairly normal for me to be playing two or three games at once, but I’ll go as low as one, sometimes four.
Usually a game or two on Switch, a PC game, and a casual mobile game with sessions around three minutes (longer than that, and I’ll churn after a month or two).
Currently I’ve got three games on the go, Crusader Kings 3 (co-op campaign), Witcher 3 (Switch), and Stellaris (single player). I had a mobile game on the go, but I quit because of the multiplayer feature - it’s not the main part of the game, but it annoyed me that I’d lose repeatedly to people who seem to be on the game 12-18 hours a day, when I can only afford 3-4 very short sessions combining to a total of about 10-12 minutes. It’s not really fun to keep spectacularly losing with no chance of winning :D
I describe myself as a little dose of toxic masculinity.
