Yeah, it's based on the philosophy, but it doesn't strictly follow the philosophy.

While this is true and works out that way, it's either put in a bit of work to get a game to run (I have epic games borderlands 2 handsome Jack collection and it crashes a lot on me) or use the store that has all the games and controller settings set up specifically to the deck. Having the option is great, but using steam is still easiest and makes any deck owners default purchase store choice for a game as steam. To the point where if I had to pay $25 for a game on steam vs $20 on epic or any other, I'd just go ahead and get the steam version if I intended to play it on my deck.
