$50 and I am bored in 1-2 weeks as I finished playing the game just I just purchased.
Seriously, in the last 15 years, I have only have a handful of games which I completed more than once. Sure there are a few games like Unreal Tornament series that i do play on and off over the years, how ever I am one of those people that would like some sort of story as appose to senceless killing and action. Like there is only so many times that i can play UT's Deck 15 before i am bored with it.
Games are like books to me. Once it's finished, it's on the shelf, and maybe if I felt that it was worthwhile looking at again, there is a good chance that it will never get picked up again.
