Half an hour is too short. Normally the games last to about 40-50 minutes (40 is still extremely rare). By the time it gets to about 45 minutes there are normally 3-5 tributes left (48 player servers). This is when it gets really boring. After about half an hour, people are still trying to get items and stuff to try and win. This is when one night has passed and the second night is about to start, or has already started. Maybe it should end after the 2nd night, or maybe the 3rd day. I agree that it is too long right now, but it shouldn't be as short as half an hour. More like 45 minutes or so as i suggested.
