Pathfinder is great. The 3.5e rules really did a great job of maintaining the spirit of the 1e rules, while addressing their many inadequacies. 4e was a real shark-jumping move, but Pathfinder carries the 3.5e goodness on.

It will be interesting to see what 5e is like. Will it be a New Coke/Classic Coke type move? Or Vista/Windows 7... where an obviously flawed product is replaced by something much better that it should have been in the first place?
