Add game duration to hover on map

When you hover over a game (to see if you want to join it), it should also show game duration (i.e. 50 turns, 500 turns, etc.), so you can determine if you want to join without clicking on it. Sometimes you click on it and the game starts before you can read the full setup. It sucks to be in a 500 move game, when you were expecting 50 moves.

Thanks for the consideration/help
