A very well fleshed out strategy game, and a great sequel too. Don't let the focus on the story nudge you away, they still have good strategy elements.

Normal people: Ok, I need to go careful about this. If I die I have to start again! Me: SLASH SLASH MURDER MURDER RAVE RAVE FUN FUN! WOOOOOOOOTTTT

This is a very fun game. You can buy guns, kill people with said guns, then get money from killing said people to buy more guns.
