If a game starts in full screen by default, it's an instant close and uninstall for me.
I see, noted!
So for when you're playing a 1st person and you want to switch windows, you just press Alt+Tab and expects the game to automatically pause, right?
Alternatively you can pause the game yourself and click away, but that would take 2 steps, so I assume Alt+Tab will be quite important.
Auto-pause on Alt-Tab is nice to have, but not a deal-breaker for me.
