I remember the hardest unlock in Super Metroid required you to beat the game in less than 4 hours. That was brutal because it was easy to get lost. I'm sure the speed runs for such games would clock in for just over an hour. My point: You could easily spend 4 times that amount of time beating the game. Though, there is that one time with Homefront. Which did turn out to be really short. Meh, you can never tell. I know you won't be able to beat Skyrim that fast unless you were really trying hard and doing nothing else but the main story. In Uncharted 3, there is only the main story, accentuated by puzzles and treasure hunting. To think some people believe they are comparable, that is just ridiculous. Bethesda said that in order to get all perks it would take a thousand hours.
