Yes, most of my PCs including laptops, and tablets have games installed on them. I am a gamer so, I like looking for games to play on my PC and tablets.
I usually prefer playing games instead of doing other video related entertaainment tasks like video, and reading.
I have like 4 games on my PC and 2 games on phone. 3 if you count Miitomo, but it's not really a game. I'm not much of a PC gamer. I just wanted to play Undertale. The other 3 I got were games that were gifted to me because I was going to try multiplayer that never happened. I'm not not much of a mobile gamer either. I have Pokemon Go, which I play occasionally when I go out for walks and Fire Emblem Heroes, which I stopped playing because it doesn't have that FE charm.
My laptop has 0 games on it, mainly because it's just for work and also because it's a bit crap to run the good games like Euro Truck Simulator etc. I would love to have a few games on it though so I'll probably upgrade the specs on it sooner or later. My phone has two games - Euro Truck Simualtor (I think it's just an unofficial copy of the PC game but it is pretty good) and Golf Clash
My tablet has a lot of games on it. As for my PC, I do have a decent amount of games but it's nowhere compared to what I have on my tablet. Then again my tablet has stuff that I've been hoarding when I found out they had disconnects, so yeah >.<
A few but they're really low-end games. They are just games to help pass the time while I'm waiting in line or I'm waiting on something else to happen. I use my computers/devices for other things that games.
I have some games installed on my Pc. I have a lot more games on my iPhone. I prefer to play games on my phone or tablet. It is just a more natural way of playing.
