Hello all. Been playing video games for a long time and thought I'd try something different. I've never played a roleplaying game before with a bunch of people at a table. I've heard of Dungeons & Dragons and by way of that I found out that Pathfinder was its spiritual successor. So I've gone ahead and went to my local game store and picked up the Core Rulebook, Bestiary, Game Mastery Guide, GMs Screen and Gazetteer.
I ran into a group that was seeking to replace their current Pathfinder GM and after talking to them for about 40 minutes, they wrangled me into doing it. So I need advice on handle this as I've never played nor GMed Pathfinder or any other rpg for that matter. I also need some suggestions for modules that are easy on first time GMs.
