Level  1 d&d game.
Books allowed: Complete and core, all others ask first and I might allow. No ToB. Running pathfinder fighters
Game will start in a small village of maybe 63 people. You’ve been self training your classes and just achived level  1. To take a new class or a prc you need to train in the arts of said class at a guild or under a master. 
To learn a feat you have to train for a certain time under a guild or someone who knows that feat. If someone else in the party knows the feat they can train you. Some feats do not need training.
The game will focus less on fighting and more on creative problem solving. 
I will be throwing monsters you can not beat in combat (At least not easily) so you will have to find other was of dealing with them. And remember, if all else fails, RUN!
