LOL THIS. I get this with 8/10 good games i come across.
Its almost asif i know its good, and i KNOW i'll get bored of it sometime, so i dont go on the game to prevent it from ever becoming boring.
End result? i just sit at my pc THINKING about playing games, not actually playing them. Im ready for my medicine now.
Took the thoughts straight out of my mind. And I really really enjoy D&D based games usually.
