I have just bought the Pathfinder core rulebook, plus a couple bestiaries and the advanced player guide and gamemastery guide.
I have a group of first-time players and am a first-time GM, however one of my players is experienced in D&D and keeps trying to add in things that we aren't using.
For example he keeps trying to add in content from other Paizo materials that we aren't using, such as Ultimate Magic and Ultimate Combat. Additionally he has tried to create his own Craft specialisation for which he wrote a ten-page guideline book. The way he wants to do it will essentially give him extra powers and feats that other PCs don't have, so I have said to him that it may need a little more tightening up to be more balanced with the rest of the group.
I have said every time that we are, apart from him, a group of first-timers and want to stick to just the core stuff until we get used to the mechanics of the game and discover what works for us, etc. I have asked if he would be patient enough to work with us and help us in familiarising ourselves with the game, at least for now. Then he tells me I am squashing his creativity and he can't play the way he wants.
He also wants to create multiple PCs and have them leave and enter the group as he pleases, which I feel probably wouldn't be a problem if we were all more experienced, but at the moment everyone is still finding their feet with role-playing and the game mechanics as it is.
We are using modules at the moment while we get familiar with the game, and he feels they are levelling too slow, based on the XP given by the modules.
I am just feeling very frustrated and am already feeling as though I don't want to play it anymore because at every turn we hit a massive discussion about he wants to add this in, or that, and so sessions are taking forever, he keeps complaining that the game is broken....
I am at a loss here guys, anyone have any advice to help me out here? I don't know whether to say, "Sorry dude, we are gonna have to play with you once we are up to your level because I don't want you to feel restricted in your play" or whether to give up and let him add in all the stuff he wants. I have tried to compromise with him by saying we can look at adding in some of the extra stuff once we've got a bit more experience in the game, but then he complains that the levelling is too slow so he can't do what he wants "for, like, forever."
Any advice?
