Well. After some searching, I have discovered that new PCs cannot be added to a game once it has begun. Which means if a PC dies, they're done. The party gets smaller. That's disappointing.
WTF!!!
I've been like okay we can work around that for most things but when I say this I was like you have to be kidding me. How the hell am I supposed to run a long campaign with friends if this is the case? Do I have to keep exporting my campaign and reloading it if someone dies, everyone has to remake their characters, and that person has to make a new one?
This completely screws everything up and means I can't make death meaningful in a long campaign!
I've been working on making a long term campaign since launch day, bought multiple copies of the game for me, wife, and daughter, and it might all be for nothing.
