So, this topic is pretty self explanatory. Anyway, what is the best single-player game you have ever played ever. I'm pretty sure mine would be Fallout 3, as I have about 85 hours on my play-through and still have not been to every location, gotten every unique weapon, every bobble-head so technically (from a rabid completionist's standpoint) I have not truly beaten it. Leave your personal choice along with the reason why.
