There's a Chinese MMORPG called Anrufen which now has an English language version in public beta testing. It's available for Symbian S60 3rd Edition phones, which includes all N-Gage-compatible devices. You can download the game's beta version free of charge on the Anrufen official website, let us know how you get on with it! And of course there's already an existing MMORPG for N-Gage phones, the old-but-splendid Tibia ME.
