The fact that Gaia's game servers crap out on me so frequently that I'm pretty much guaranteed to never be able to finish a game properly. It's really aggravating to sit down to play and then have your experience repeatedly interrupted. This is why I don't normally bother with the games, and also why I am sitting on a pile of tokens the height of Mt. Everest.
So much for idling away a free hour before bed. xp
