SHHHH!!! Still in the plastic! I use the wiki if I have a question - but there are obvious and permanent changes to the game depending on what you do.
I am stuck as a damn vampire right now - think I got bit by one, cause I intentionally avoided the quest line. Need to do the quest before I hit day 5 to take it off - I didn't know I could use a potion at the time......I am on day 3.
