my experience at PaizoCon left me less than enthusiastic, in fact I'd say I'll pass on the game at this point.
While the idea of three actions per round was graphically pressed, I'd remind people that 3.0 started with just free, move, standard, and full round actions. It differentiated and developed from there adding swift actions. There is no limit to free and swift actions (an issue IMO).
Wizards with just 3 spells AND having them limited to "in round" or single event effectiveness is unacceptable. The spell system was very undeveloped and disappointing, Shield spell is a one shot where you are better off with a 3 or 4 small metal shields and dropping them as they become ineffective. At this point in time wizards are ineffective.
Clerics were a bit better as clearly healing had been looked at and expanded in some ways, not in others. The spells were a disappointment(but not so bad as the wizard spells) but more time seemed to have been spent on the spells.
The whizbang factor of goblins is a don't care, so long as the class is balanced. More of a PR thing of having something that you couldn't have before.
