I have had the same experience, logging on to find a large number of games needing moves. My list is sorted by time remaining to move. If an opponent in a game with a short time window happens to be online and sorts his games the same way, then we will be passing moves back and forth rather than working through our other games.

This can be disconcerting if you have it in your head that you have to get through all the games that were there when you logged on. However, if you think about it logically, do you really want to bury the game with the shortest time window under all your other games, just because it is also the one in which your opponent moved most recently? You will still have the same number of games in your list, regardless of which one you choose to move in next.

The way I think of it, I have a certain amount of time for playing, and if I don't get to the games with a long time window, so be it. Those are the games that can wait, by definition. I will play the most urgent game first, regardless of when my opponent moved.
