well, I've been looking at Kaneva Game Platform. Its specificly designed for MMO's, and can be tweeked for mmorpg's and such, which is what I'm attempting for my project. I wouldnt call it very user friendly though. but seems to have some good points.

Might still be down for revisions to the site
I'm looking for a real easy engine to make an MMORPG though that still has real good performance visually, anyone know which one's best?
