We just had our second gathering to play Pathfinder (Pathfinder is based on the D&D 3.5 Edition Rules). We started playing the Curse of the Crimson Throne adventure path last weekend. I'm the gamemaster (Dungeon Master) and I've had a blast.
It takes a lot of preparation to get ready for a game. Lots of printing and lots of reading. However, it's worth it. I want to make sure the players have as much fun as possible.
I can't wait for the next session as we had to stop play in the middle of combat.
Pathfinder is an incredibly detailed game and the content from Paizo is amazing. The story we're playing is very well written. I can see why it's one of people's favorites.
