why you allowed to start a game 10 mins before shutting down the system

just how much annoying this can get,you still can start a new game without knowing the maintenance time is counting down. Then at the middle of the game, you just shut the entire system down. DONT TELL ME to check the tiny little ! button each time before you start a game. I WILL NOT. Especially when you are playing good,or feeling can get a higher score. This is just discussing!
