I gave the free PDF a skim, and these house rules look pretty good. I like how they've separated out combat feats, I like the skill changes (and the expansion of Perception to include smell, touch, and taste), I like the strong flavor of magic schools, and I like the WoW-inspired new look for the races (and the additional racial details, like Dwarves getting +2 to perception checks related to the sense of touch). Pathfinder seems much more granular than 3.5 and I dig that.
The art and layout are both FANTASTIC. Sarah Robinson did an excellent job in selecting existing pieces and commissioning new pieces from a bunch of skilled artists with different styles, yet consistent feel. Gorgeous product, especially given that it's an alpha doc.
And kudos to Paizo for the open playtest. I don't think an open playtest is a good idea for a brand new ruleset (you'd run into non-helpful feedback like "it's not like the old edition!"), but for improving a existing edition? Good choice.
It really is a cool-looking set of rules, and Paizo's enthusiasm and passion for the game is a treat. If I were at
all interested in continuing with 3.5 I would totally playtest Pathfinder. I'm not; after nine years of the same game I'm ready for a shiny new edition. If 4E turns out not to be to my liking I may come back later and see how Pathfinder development is coming along. Or I may just take some of the ideas (that change to perception
is cool) and use them in 4E.
At any rate, Pathfinder sounds like a really good salve for people who've already made up their minds to hate on 4E. I'm grateful to Paizo for that.
