I finally started to learn a little about LawMaker engine as I purchased indie about 4 months ago, and I can tell you that I regret that I lost so much time to learn it better.
It is simply fantastic!!!
I read just their manuals from WIKI page and sudenly I felt that I worked with it for months. Everything is so clear and well organized, starting from creating Sollution file and adding resources to your project.
LM consist of 2 folders, one for keeping all your assets and second for keeping compiled stuff. So everything you load into your level from assets folder and compile it, its automatically goes into second, ready-to-go folder. Everything is well organized and you can find assets in a second.
If you are planing to make FPS, there is already player script completely done, together with superb AI with almost no programming required.
Exporters for almost all "big" 3D packages ensures us very easy workflow.
Engine is very fast, and shadowing system is fantastic.

Working with Editor is very easy and you will mastered it in short time.
As soon as I learn something more I will write here.
Its time to look some coding tutorials
