So Payday 2. Im just gona start of by saying that this is one of my favorite games ever.
Pros:
Its a ♥♥♥♥♥♥♥ bank robbing game
Great CO-OP game
Massive amount of weapons and weapon customisation
Easy to ♥♥♥♥♥♥♥ hard difficulties making it so that pretty much anyone can play it
Skill and perk system that can change your playstyle things like Dodge, Armor and Stealth builds
Challenging stealth
Mountain of replayability

Cons:
A skin system akin to Counter-Strike only difference is that you don't need keys to open safes
The ♥♥♥♥ ton of DLC, the fact is that DLC funded this game originally and because of this there is a ♥♥♥♥ ton of it. The game is playable without since the DLC heists can be played if the host has the DLC.
