Extremely good game. It has great details, realistic aspects, the story and characters are quite captivating and realistic, the take on the folks in Montana is frankly hilarious (as a Canadian I couldn't stop laughing) and the sheer amount of things you can do is great for many playthroughs.
Finished the game the first time? No problem! With new game+, after completing it the first time you can unlock the 'infamous' difficulty, which is super challenging and incredibly fun.
My only real complaint is the stealth. See, in other games like payday 2, when a guard notices you, you still have the chance to silence them before the rest of the group is alerted and the alarm goes. In this game, even if they didn't shout, shoot or even gasp in suprise before you popped them off, the entire area is instantly alerted. This can be super frustrating, along with other detection bugs. All in all, 100% recommend, you won't regret it.
