Its one of the most time consuming games that I ever played. You can go straight and complete your mission or you can endlessly (especially with 1.13) sandbox around. For me it always was kind of a dress-up-game. I'd stuff my mercs into the nicest body armor and give them the fanciest accessoires one could find on the battlefield and then show up against Deidrannas red shirts. As you progress throughout the game your gear gets better and better and when you finally enter the evil queens palace you'll be the Kim Kardashian of daydream commandos and wall ninjas... if they do not kick you in the butt before you get there.
