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.
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.
