Only a madman would try FTL without a quick pause, although I believe it can be remapped.

Even if you own a Steam Deck, Nintendo has some attractive value. Nintendo essentially has a monopoly on at least 3 genres of videogame. The entire library of Steam doesn’t really have a casual racing game that can go toe-to-toe with Mario Kart. The same can be said for almost any Mario game. Even if a Steam Deck had the games, you’d need 2 decks or an extra controller to get the Switch-style experience. Valve isn’t really trying to compete with the Switch on its own turf.

It’s a common trope in videogames to make a boss fight’s weakpoints pulse a different color to make it clear you should shoot there.
