One very interesting change they made was to up loot drops-- apparently Western players felt they weren't getting rewarded the way they want to, so Codemasters (who publishes the game here) doubled the drop rates, not once but twice. On the other side of this, they've gone RMT to make the game free to play-- players can play real cash for ingame money used to buy ingame items. For some reason, that's flown in the Eastern MMO market, but not here so far-- it'll be interesting to see how RF Online players get into it (or don't).
Unfortunately, none of the interview actually focuses on whether RFO is any more fun to play. Then again, it is free now-- you could do worse than to go grab the download and check it out for yourself.
