@tabsina, I'm not totally sure, but thinking back I imagine it took about 4 hours total, though a further hour sorting through the numbers on the laptop then adding them to this post.
@Oyvoyvoyv, Your Sports to Play ratio just doesn't seem natural, I would be the first to argue Wii Play is well worth the money you pay for it but Sports is so much more incredible.
You seem to have liked The Godfather:BE... even if you are correct that you left it for 30 hours you still played quite a bit, I may have to look into that game, what is it like? [I believe it's a sandbox type game?]

Regarding any time I have left a game/channel paused: I don't think it would be much overall, I think twice or thrice I've left it for 30 minutes on RE4, probably about an hour total for LoZ, and another half-hour on SSX.
Then in those 5 days of February 2008, I left the voting channel on for almost 30 minutes, and Z&W about 30 minutes too.
So probably only 4 hours left paused, I don't like to leave things on when I know I'll be gone a while.
