Some call it D20 Light. Some gripe that it's so much like OD&D that they can get OD&D clones for free.

Bah!

I call it Light, all right -- Light hearted and fun! What gives PFRPG its edge, is the fun and almost-whimsical tone of the writing. The style is friendly and encourages reading.

As to playing -- Well, a lot of people like the Knacks. It's a good skill system which doesn't go off into Feat-land, a place which still gives me shudders! The various classes are fun - there are some which are significantly strange that I'd love to play them.

There are some quibbles with realism. My experience is that a person in combat who goes berserk is going to take MORE damage, not less. That's why we trained so thoroughly, so that when a panic situation occurred, we would NOT go berserk. Trust me, I've seen people (fortunately, very few) who "lost it" and became real machines of destruction -- but left their defenses wide open.

I could see this ruleset encouraging good roleplaying and well-structured adventures. Unfortunately for me, I really can't see myself using PFRPG when my two favorite FRPGs (Castles & Crusades and Tunnels & Trolls) cover everything I want or need in a fantasy RPG. There's nothing here to really pull me away from either of those two. And nobody's selling extra hours for the day or extra days for the week....

If you haven't found your perfect rolegame yet, or if you're willing to try something new, you could do worse than try this game. Unlike most rulesets, it's fun to read. And you might get a few good ideas from it, even if you never actually play it as written.
