If I can't get more adventures, then more settings would be good. For example, Ghostwalk has my interest piqued. Not only do I get a new game setting, but a set of rules that relate directly to that campaign! To me, this is the best way to introduce new races, monsters, prestige classes, etc. It also gives a great balance of rules and flavor. IMO, monster books and splatbooks have been done to death. I go into an instant MEGO state whenever I look through a book filled with tons of new prestige classes or monsters. It's information overload....and then on top of that, I'm supposed to figure out if these things are unbalanced?! No thanks...give me something new...something that shows some creativity and not just a good grasp of game mechanics.
