Did you tried Antiryad GX? Easy to install but I never figure how to use it.

Antiraid, is very old, even if it can do advanced technics !
It's world editor is even more worst than 3DGS
Lots of things displayed all around , any panel, hard to use i find.
It's an engine passion by it's author not a real professionnal engine for delivering games around the world !

I liked the looks of some of the things that were made using antiryad, but I still think leadwerks looks more attracktive.

Seems like no one knows much about leadwerks here though...

lua scripting... I'd love to do that

I have leadwerks engine, it looks awesome, but after upgrade to ATI card the engine doesn't look OK anymore, I don't use it now.
