The top 100 list has already been posted, but I thought this article makes some interesting observations on the list.
Overall the variety of games and experiences on that list really show how versatile the deck is, and that people can still have a great time with games that aren’t a perfect experience on the deck.
Steam did try to hack Wine’s handling of windows textboxes to automatically trigger the OSK. I’m not sure if they gave up there (or I got lucky in disabling it), but it suuucked. It’s very easy to get into fights with that auto-popup, particularly if you’re trying to do wine-tweaking tasks.
