I find that many experienced gamers like to play more advanced characters and adventures. I personally like to start my players and my own characters at 4th to 6th level, depending on the setting. for example: a Ranger campaign would have to have a starting level of 6 to have a PC that has just one level of the Anla'shok PrC. What do you think? What do you think is a good starting level for a more advanced campaign?
