The grind is even worse (more boring) than L2. Especially post 30. Horrible environment graphics, (the character art is decent- that's why it's always the feature of screenshots, not the environment) less character customization than L2, mindless combat with only one or two powers for 30 levels = fun for Koreans, but crap for the rest of the world. PvP is interesting the first few chip wars but not enough substance to make you want to do it over and over. Imagine being stuck in Thidranki or Warsong Gulch forever fighting over the same ground and nothing changes.
Drilling holes in a rock is about as entertaining really. Definately an avoid at all costs for RPers or players looking for deep gameplay, immersion or a challenge.
If you must have a SCI-FI mmo... try Anarchy Online or EvE, they far surpass the overall quality of RF.
