How about a cup of coffee? You have been playing for two hours.
It’s four hours in a row! Time to stretch your legs!
You’ve been playing for six hours already! Bet your empire will be fine without you for a moment or two.
You’ve been playing for eight hours now. You do know you can turn this off, don’t you?
Time flies! It’s been ten hours! And there is no time-based achievement to await you, honestly.
Twelve hours. Seriously? Turn the machine off this minute!
Twenty-four hours and the game is still running. You’ve reached the end of line. No more play time warnings. Let’s hope you pressed fast forward and left for bed, so I am merely talking to myself right now.

Oh I didn’t know this goes so deep. I think I only had the 6 hour one a few times. 24hours is crazy.
