Edit a few hours later: I just want to thank you all for a nice discussion of the topic, I certainly learned a lot about how things work in the background. Doesn't change how I find it annoying but it makes it more understandable!
Just need to vent this into the great emptiness that is the internet. What is going on with providing proper save capabilities in games today? Is it really that hard to save the state the game is in, when I exit it? It seems to be, because I keep seeing games where only at specific times an autosave is triggered, and honestly, it's annoying.
Latest offender, The Fall of Porcupine, actually looks like a cool game, if you would actually be able to save when you exit it. Instead it saves at seemingly random times. Now I am trying to play that with my kid, and we got to watch our screentime a bit. It happened now twice we weren't sure how to trigger a save by going anywhere, nothing we could do would trigger it. So we lost progress... again. Probably not going to continue this one.
Even really great games do this. I finally got Dave The Diver and at least you get to save on exit everytime you can exit. What I didn't know until playing it for a while, there's times where the game does not allow you to exit, what in the world is up with that? Apparently it is really really important to finish this silly cooking minigame right now, as there is no option to return to menu. Similar in some other sequences of triggering a boss fight. Just now I was at a place in the game where 3 separate boss fights got triggered with no indication its going to happen and of course no way to exit. Other than killing the game, but I guess that wouldn't save it.
Aaand Stardew Valley, I really love it, great game. But only being able to save when ending the day, seriously? I read the mobile version can save anytime, why not all others too?
Ok, done, you can now ignore me or share your own stories if you like...
Yeah, OP, based on my experience with the Deck, for a vast majority of games you can just go to the ingame pause screen, press power button to "sleep" the Deck, and then resuming later has no impact.
There are a few games that maybe had audio issues or something after resume but nothing major if your main concern was simply avoiding losing progress.
True, but then you have to keep playing the same game in order to do that. Doesn't work all the time either, at least for me. I do appreciate everyone does this their own way so I think it is great that this works comparatively well.
