It's not search and rescue as such, but Snowrunner is a cool take on disaster recovery. The action comes from a weird place, too; driving slowly over difficult terrain. You need to react quickly and keep your wits about you all while doing 4mph. Crawling through mud in an eight-wheeled truck while desperately trying not to tip over.
It's an odd mixture of relaxation, sheer frustration, and job satisfaction. Oh and there's plenty of gear porn if you like ridiculously powerful machinery too.
Is there PVP? I'm always wary of bothering with these sorts of games if they have open PVP, as they usually turn into mass slaughter pits where the players who have built up powerful armies (or whatever the game has for units) go around murdering weaker characters just to see the inevitable forum posts. If you make it through the early stages and join some sort of alliance, they usually turn into childish playground politics and squabbling.
I couldn't tell from the "about" or "FAQ" pages, but the meme-filled forum doesn't make it look particularly promising.
Compatibility is always touted as the primary reason why Windows trumps Linux for PC handheld gaming, but I'd say that the Steam Deck is probably more compatible with the types of games that I play than handhelds like the ROG Ally. Sure, more games may run outright on the Ally, but how many of those are genuinely playable if they rely on a mouse for control? These are supposed to be handheld PCs but for most of them you'd need to plug an external mouse in and sit at a desk to get the most out of a large number of PC games. Touchscreen control is often awkward at best for management games and games with similar mouse-driven interfaces.
I think the Lenovo handheld has a touchpad from the looks of a few photos, so at least they've understood the problem. If you play the sort of games where you'd mostly use a controller anyway you've got a lot of good handhelds to choose from. If your game library looks a lot like mine though, your choice is limited.
