I am well aware that when someone starts a discussion with, "I am not trying to be a ____, but" it usually means they are, in fact, a ____. I hope to be an exception.
I don't mean to be a spoilsport, but how many people on these forums, or who are among the 15,000 downloads of Pathfinder Alpha 2 so far, plan on buying the release product?
I am generally pleased with everything I've seen, and I can't think of a single change I dislike. However, it's one thing to see Pathfinder (or, for that matter, Dungeons and Dragons 4) as an improvement over what is currently available and another to consider it such a notable improvement as to be worth a purchase.
For the sake of the gaming industry in general, and the obvious hard work of the people at Paizo in particular, I hope my discussion is met with dozens or hundreds of pledges to purchase the finished product. I just want to be honest - I like it and I like it more than DnD 3/3.5/what I've seen of 4, but I don't like it enough to buy.
