quiting, whining and general incompetance
Inherant in every multiplayer game.
My suggestion. Build up an extensive friends list in ICO. Dont be exclusive with it either. Just add anyone who doesnt quit prematurely , who fights to the end , who are competant at the game , who can strike up a mature conversation in the lobby , who dont whine in the game etc.
Circles are forming in Sins , so its best to find your circle.
