Well to a certain point its fun to gather more and more points so that the unlocks come fast. But right now, I think I'm at rank 49, there is nothing left to do for me. At least I'm not interested anymore in the unlocks I havent reached yet. And my K/D ratio is well above 1:1.
So the fun is beginning to fade I have to admit.
I think I'll play the remake of Jagged Alliance 2 next. I loved that game back in 99, and if they stayed true to the game mechanics but with better gfx then I'm all sold.
