1.7 minutes average... I didn't like ACDC.. found it to be a drain monster and so just couldn't get into the game... flip side BTDK and Transformers are the complete opposite and I walked away mid game as I just couldn't lose a ball at all! Transformers I did 10 minutes on the first ball and left the rest after deliberately allowing it to drain.. REALLY didn't like that game.
Mind you Brett.. that is a new game and in all honesty, 5000+ games should be expected without fault
