Alright, one of my players and I are having a disagreement. He claims that because it is "his" game, he should be allowed to make any house rules and override any and all FAQ rulings that he thinks are unfair or stupid (he's already changed pit line of sight to where only creatures adjacent to the pit can see the hero inside it). I, who am the OL, think that I should get final say, but he comes back with the fact that I'm not a DM or God in the game. The thing that sparked this debate? Tattoos. He doesn't like that the Tattoos are being elliminated. He's also been trying to allow him to alter Nanok's ability in RtL.
Yes, he is playing Nanok, I foolishly allowed him to before I realized how hard it is to deal with him during Campaign. He currently has it in his head that Nanok is underpowered because he doesn't get any abilities from armor, and that he either needs more armor (increased bonus from silver and gold power dice) or the ability to wear armor for their abilities and foregoing their armor.
So my real question is, who should get the final say? I'm slightly ahead in CT because of a misread of the rules, and am planning on compensating them with one treasure each, but Nanok in his current state will give me trouble for all levels of campaign...even though the player claims I'll have no trouble killing him with monsters that have piercing.
Should I get final say on house rules? should he? should the FAQ? I just want people to come to an agreement, because he's the type of person who will make up his mind, and run a game into the ground if he doesn't think he's getting his way. He'll just keep pulling the "Well it's my game, and I think that's stupid" card. I NEED HELP!
