This game has endless hours of fun, exciting content, but there is a ton of grind.
You'll have fun experimenting with different combinations of weapons and skill point allocations in order to maximize your efficiency VS the game's police force. Stealth is there too, but I always want to tear my teeth out trying the harder ones (you can probably do them easily if you're patient unlike me!)

The game has a maximum prestige (Infamy) amount of 500. To go infamous you need to reach level 100. So you have to beat the game 500 times to truly finish it. However the higher in infamy you go, you get unique, exclusive rewards as well as permanent XP boosts to help you get there.

Oh yeah, and DO NOT BUY THE BASE GAME ON SALE! THE GAME IS GOOD AS A BASE GAME BUT YOU MISS OUT ON A LOT MORE CONTENT WITHOUT THE LEGACY EDITION! I'M TALKING A TON OF HEISTS, WEAPONS, AND CHARACTERS!
