I am finding that the PS3 game is a little glitchy but the glitches are different by character and not by the game. Here is what I mean:

1st character. started mian quest did companions then civil war for some reason bards college would not let me move forward because I could not pick up the ruby claw and use it. Did DB but could not finish TG because Mercer is still in the Ragged Flagon even though I broke in his house. Wound up roaming which is the best part of the game.

2nd character. Started with companions and then TG (loved finally killing that SOB Mercer). Civil War and Bards college. Here the college would not let me bring back the focusing crystal to the mage college and even had to back door the staff of Magnus quest to get the staff and mask to get all the preist masks collected. Now the DB will not start as the little clown will not speak to me and no barkeeper in all of skyrim will even start to discuss that little demon child who has issues with certain advlts.

The question is: is this common place? and is ther somthing I can do to retrigger the start or the line of events to allow me to conitnue with the stalled quest lines?

Have you gone to the Aretino residence in Windhelm? There is a scene between a mother and child right outside the house that can start the quest. Alternately, just break into the house and see if it will start that way.

Not to be a [censored], but this thread probably needs to be in here: http://www.gamesas.com/forum/182-playstation-3/

Since we are talking about glitches and such.
