How many of you install games outside Steam on your Decks? Do you find the process easy?
I'm a hobbyist game developer myself, and I'm looking into making games especially designed for the Steam Deck. However, for freeware games, the $100 price per title on the Steam store is a bit too steep. I wish there was an easy-to-use alternative store on the Deck, but since that's not the case, I'm wondering if it would make any sense to develop games for the Deck and publish them, for example, on Itch.io.
(As a proof of concept, I created this step-by-step guide for a hacky Steam Deck version of my old game, Soccer Physics. I think it still applies, even though it's a year-old build/guide: https://www.ottoojala.com/soccerphysicssteamdeck/ )
Personally, I'm just not into that solo game dev career anymore, been there done that. It'd basically require for me to start up my own business again, thanks to Finnish laws. Good point about the steam keys, hadn't thought about those at all :--)
I have no solid plans for a game specifically designed for the Deck yet, but I'm really into local multiplayer games, and do think a game that you play on a shared Deck might be cool. For example a game with just joystick controls - one stick for each player. My background is in making local multiplayer mobile games and I feel the same kind of games would work just fine on a Steam Deck, too, with the hardware controls adding new possibilities for designs.
