I am unsure of what you are looking for here. I started DND V3 almost 20 years ago, I own a large amount of books and played and mastered many games. I stopped when 4th ed came out because it sucked. I picked up pathfinder about 5 years ago and got into it for a bit but I had other more important things to attend to and fell out of role playing.

My advice is this. Play Paranoia. Pick a game master who learns the game inside and out. DO NOT LET ANY PLAYERS LEARN THE GAME RULES OR SYSTEM OR STORY. The game has authority classifications depending on what rank the players are that can let them be privy to some rules and lore. Trust me.

DND and even pathfinder are slowed down extremely by rules and arguments will come out between players and masters when the masters accidentally slip up and screw the party because they got a rule wrong. If you want to look into the game but are unsure if you want to master DO NOT READ ANYTHING ABOVE INFRARED LEVEL.

Discuss anything you want.

That last sentence of the most recent comment.

Of course, in all of these, God has provided the correct calculations.

Something tells me this is going to be an interesting read.
