the game is indeed very awesome! haven't played it in a while, but i'm trudging through as a Priest!
Good news from Atlus, they are extending the online component to Demon's Souls until at least 2011, so hooray! they are also having a White Soul Tendency thing to celebrate it!
this game is definitely one for the PS3 collection, and one of the best parts is that the game is great both on and offline!
