I don't want to spoil anyone's fun and, by and large, I think the comments we're seeing on the Alpha Release aren't in this vein, but I feel compelled to say, both to Paizo and to my fellow enthusiasts for this project: let's remember what this project's goal are.
The Pathfinder RPG is intended to be a natural evolution of v.3.5 that corrects its most clear and problematic flaws while placing a premium on backward compatibility. Consequently, some things that you or I may not like about v.3.5 -- iterative attacks, for example -- probably can't be changed, or at least can't be changed with ease without calling into question the stated intentions for the new game.
I know everyone excited by this announcement; I know I am. But we have to remain focused on the immediate project, which is correcting the universally acknowledged inadequacies of v.3.5 without creating a new game that is so different from it that the vast library of D&D and D20 books produced over the last eight years are completely worthless.
My apologies for the bucket of cold water, but I think it needs to be said.
Now, on with the fun!
I'm of two minds here. I agree that the very best thing would be backwards compatability that allowed me to use my existing bookshelf, but how many people dropped all of their 3.0 supplements as soon as 3.5 came out? Is backwards compatability truly do-able? If it is, than I want Pathfinder RPG to "fix" the rough edges of 3.5. If it's not do-able, than I'd like to see the Paizo gang open 'er up and see what they can do.
