Pathfinder was made by people who prioritise fluff over mechanics and is based on a tweaked 3.5 core. If that sounds very good, it's probably for you. If it sounds horrible, avoid.
Change that to "mechanics supported by fluff" and I think your accuracy rating rises signficantly.
I love my game mechanics. The Pathfinder Core Rulebook is fairly fluff-free and downplays Golarion influences. The rest of the Pathfinder line freely mixes crunch and fluff.
