In my opinion, this is the ONLY 3D MMORPG worth mentioning that's compatible natively on the Linux platform.  Apart from that - the game mechanics really stand out. 

Instead of grinding away to level 100+,  experience is gained on several individual skill sets.

If you liked Privateer ( the original game) you'll love this.

Agree with it. Game client pretty stable and run on 32 and 64 bit both ok. Only bug noticed with voicechat + pulseaudio, though folks in game told me about workaround for it.
