forgive my plot hole but...

...why don't they just take off their helmets when something bad is about to happen, preserve their characters and log back into the game when the bad guy is asleep or something? And why wouldn't they just trade the same helmet between a few people playing on the same character so they can go without breaks? I just don't understand the rules of the game and that usually wouldn't bother me except this movie forces you to think that the game really matters but it doesn't make any logical sense!!!
