When he was creating his character he asked me "what are high elves like?" and so I described them as such as said thats what he wanted to play, when in all honesty hes doing what most wood elves would do in my setting, its really not important for any reason other than the hook that got him there...
if he does this it contradicts him being there, which means more work for me....honestly i dont care what he does with his character, even though in the end there is a good chance he will save the high elves and stop them from being xenophobic...so pretty much that part is fine, and I worked it all out with the land bs he wanted and yeah...alls well that ends well....now if he didnt want a unicorn mount too i think things would be easier
but I think most of it stems from that he plays single player games and that where it isnt about just your character, its about the team, I think a little more of the rest of the group kinda saying 'what about me?' or even 'can I do what my character wants to do?' (that last part came up when our party's rogue who can speak goblin was interogating a goblin and the elf, who does not speak goblin, was telling him what to do...that will get hammered out in time i guess)
that and he only owns a copy of the player's handbook so i can kinda be like "but in the DMG it says..." and not lie...but pretty much bend teh rules, not against him, but so its like "look....i have to roll up the treasure, make the dungeons, all the NPCs ALL OF THAT STUFF and the last thing I need is you thinking you can make money off of starting a town"(he actually wants to make a town and make money off of it, which kinda directly goes against how the human government works....since its a monarchy and the king more or less gets that money, but hes a fair and just king who spreads it around where its needed and that kinda stuff, that and thanks to me having a history major for a brother and his class on robin hood, the 'peasant' has rights...such as those to keep what money he makes so he can spend it. Itd be a utopia if not for dragons and orcs mauridng on a weekly basis

)
that and I decided to refine my treasure stuffs, like less stuff to sell, more stuff to find that interesting use for, so a lot more wonderous items (since who doesnt like those??) and im going to try to introduce the 'roll for it' doctorine my other group uses in which if you want something and another person wants it, roll for it, whoever gets higher keeps it.
That and talk to the rest of the group about what exactly things do...the cleric does not need gauntlets of ogre power when the fighter or even the OTHER warpriest could benefit better...but once the wheels start going on this campaign and more is understood then I think (and hope) it will go smoother, just the newbie hickups right?
