I found ATOM RPG very enjoyable. That's one you've probably missed as it's from a small Russian developer and not very well known. For a quick rough idea, imagine a Russian game like Fallout/Fallout 2 (but with modern graphics, obviously, as it's a recent game). It might well be the best game I've played in the last couple of years. Almost certainly the best value for money since its full price was (and is) £11. I liked it enough to give the devs extra money for the "supporters pack", which is just a way to give the devs extra money if you want to (and explicitly labelled as that - you get an ingame knife and outfit for it, but it's not macrotransactions BS). They're working on the sequel at the moment - Trudograd. It's on early access now, but I'm going to wait until it's finished. Unlike some companies, this one actually finishes a game before saying it's the release version.
EDIT: To clarify, the game isn't in Russian (unless you want it to be). The setting is Russian, but the game is fully (and competently) translated to English with one exception - signs on buildings in the gameworld are in Russian. Which doesn't matter and it would be jarring if English signs were put there instead.
