I play a lot of windowed games on my PC as I watch less engaging content like TV I’ve seen, Youtube. Lately Balatro, Peglin, a racing game called art of rally, Mini Motorways. Interested to hear other people’s preferences.
I generally want something that runs well windowed because I use a third of my ultrawide to run the video, so no shooters or “big” games usually.
I really only play games that demand all of my attention. Though if I am playing something with constant down time, like being dead in Counter-Strike, I’ll watch YouTube videos on the Steam overlay until the next round.
