Think the topic kinda covers it. I'm going to run a Epic level game where the PC's are basically liberating a continent from the vampire scourge with the help of a small kingdom + some army enforcement's. That's the plot in a nut shell. Everyone thus far is running a PC class, but one of my players asked to play an Ancient Gold Dragon. I thought about it and said I would be willing to let him run an Old Gold Dragon (HD 22) if he really wants to play a dragon. I know the main reason he wanted to play Ancient Gold was because of the At Will Sunburst, and I wasn't about to let that fly. He seems chill with it, but wanting to know what others might think. This is kinda what I'l winging it thus far for all PC's...
Stats are rolled
New Characters that are rolled get 800k gold
Characters that are continuing from another game get all their gear + 400k gold to spend (They were plane shifted to this world knowing it's plight.)
All PF books are good to use + traits + archtypes
Characters are level 20
22 HD dragon seems to be kinda on par with a level 20 character. I'm going to run a few "test" adventures before they go on the main story to get a feel of party balance. About 5-7 person party + npc's if they want.
