Why is a three year game a bad thing? Think how long mail correspondence games used to take. That old game hanging around becomes a trusted and reliable friend after the first 10 moves.
You can't abort a game for abiding by the time controls. That just seems uncool somehow. Don't know why - just rubs me the wrong way.
Both side to make one move is x2. One move is 13 days x 2 = 26 days per move. Then suppose at least the game should ended 40 moves x 26 = 1040 days. One year has 365 days that count 2 years plus 310 days nearly 3 years per one game. Oh ho it can turn my beard to white. Yes better is before it continue the game "aborted" is the best answer.
