Pathfinder Roleplaying Game

When D&D 4th edition was announced it was immediately accepted with a lot of negative feelings by a rather large number of people. Realizing a lot of 3 and 3.5 material would suddenly become mostly useless and that Wizards will be making a significantly different game, Paizo Publishing decided to cash in on the 4th edition naysayers and appeal to the people who wanted to stick to the old edition, but realized it still needed fixing.

Thus Pathfinder came about, usually called also D&D 3.75, due to the fact that it largely resembles the 3.5 ruleset but with various non-drastic updates, fixes and changes.
