This is a great quarantine game
I've played the game on launch, I have played the game on 3 different accounts, and I've sunk in over 400 hours.
what can i say, the game isn't perfect, sometimes you might encounter a glitch in the game that will look odd(not game breaking), Maybe find an enemy that isn't functioning like supposed to(found like 4 of these in my 187 hours of playing), or clip through the map because someone setup their base like that.
The game is significantly better than when it launched, almost all the game breaking bugs and glitches are patched, and the game sometimes stutters in White Springs, but that OK. The game is playable and runs pretty well on a GTX 1060. This game can be played single player or with friends(My steam play-through has been 70% solo) and it's fun. another thing about this game is that the community is incredibly nice, sometimes they'll drop ammo, help you with side missions or quests, or help you build that armor that you've been grinding for. The game receives monthly updates and there is always something to do in the game.
Wastelanders added a ton of new stuff, new weapons, more NPC's, and tons more content. I still plan on playing this game and updating this review depending on how the game is at that moment.

game is good so far, my first save was 4 hours long, and on my current run i'm 42 hours in and i haven't explored most of the map. overall great game and i'd recommend you buy it

R6S is a great game to play!
