ArmA 2 definitely got me hooked. I spent 950 hours playing ArmA 2, finally I am just about done with that game, but I am moving on to ArmA 3 which will probably take up even more of my time! I spent so much time on Life mods, I would say I spent about 300 hours on Island Life, 400 hours on Takistan Life, then 250 hours on other things that are not those 2 life mods.
