Long gameplay lovers? This would interest you!

I am a game lover, though not skilled.
Played a number of FPS games recently, though most of them had short gameplay, finishes it within 2 days, LoL.

Games which I finishes within 2 days are:
Call of Duty: Modern Warfare
Call of Duty: WWII
Rainbow Six: Vegas
Rainbow Six: Vegas 2


Recently I'm playing Fallout 3. It has long gameplay. I had played it for almost a week, and I am nowhere near the ending I guess. Though it has TONS of BUGS. People in a certain town attack me when I am not doing anything, LoL.. Character got stucked in certain places, and etc.

Nevertheless it provides a long gameplay, which I strive for. If you can bear the bugs, this game is a go for you~.
