Well the only big thing i see, is it's Network part , that sounds solid !

I tested their new demo, the problem is that is just a really too simple room with some stuff , not a real gameplay demo
And it really don't run smooth like hell !
It's an empty simple level, without real shaders, no animated ennemies or NPC, no particle effects , no HUD.

They should make like Unity a real convincing gameplay demo level with all stuff, if they really want to attract people !
