PlaneShift is probably somewhere between alpha and beta. Beta is usually when at least 70% of all features are in and the main goal is bug fixing, in a traditional sense. PS is only at version 0.3, so we're 7 version away from being 1.0. There are no classes in this game, but rather a skill-based system: you train any skills you want, in whatever combination, and thus your only limitations are time, effort, and preference.
Every fantasy MMO looks like WoW, or maybe WoW looks like every fantasy MMO

They're the biggest out there, but PlaneShift is definitely not a WoW clone. We encourage heavy doses of roleplay.
