I got it because a RL mate got it and wanted me to play with him. I found it to be an un-inspiring version of WoW and AoC, lacking the great quests of WoW and while having similar graphics to AoC, i felt that the soundtrack was rubbish and i was just unable to immerse myself in it. I think it'll survive as an mmo, there are no low-pop servers as such, most are medium pop. Economy seems fairly stable, not as developed as WoW's naturally.
Overall a 5 for me. On the other hand my friend really liked it.
