Hours? HOURS?!
I intend to play for far more than just hours!
Yeah, i intend on spending a lot of time playing Skyrim.
Well that's pretty meaningless. Any length of time can be measure in "just hours". You can measure the age of the universe in hours.
Anyways, as for myself, I put about 400 into my main character on Oblivion, and totaled about 600-700.
Morrowind, WELL over a thousand, and still counting.
Since I can already tell this game will be better than Oblivion IMO, I can't imagine putting less time into it, so I voted 600-700 as a conservative estimate.
