My startup was based around Flash-gaming, and our traffic numbers (to the extent that we had traffic, which wasn't enough to keep going but was enough to see some patterns) showed that the vast majority of hits occurred between 9 AM - 6 PM Eastern, Mon-Fri. Tailed off until about 8 PM (my guess is those were the west-coasters), then we'd have very few hits at night or on the weekend. Funny how that works. ;-)

OK some games, but I am yet to see anyone playing Civ 2 during work hours, or Alpha Centauri. That would sure make me laugh.

And then cry, if they are on your team. 5-10 mins of a flash game during a break ? No problem, it will help them relax. Several hours of FreeCiv (and Civ is a huge time-sink) ? Not during the workday, God no.

But I promise I'll stop once I discover Gunpowder!
