The game is stable now after the updates, still needs a decent pc. Single player is fantastic. The multiplayer has almost no content right now and it's the same grind as GTA. It feels exactly like GTA Online but no content.
you can always playtest it and buy it afterwards if you deem it worth buying.
you can also pirate it and buy it when its on sale.
I don't trust any game or developer enough nowadays to shell out 50 bucks for a chance I *might* enjoy their game.
