This engine is the code behind "The game Creator's" FPS Creator development tool, A powerful, yet rough FPS engine.
This is a very good engine for beginners and advanced users alike. I have been making games with this for a while, and it is one of the few "good" game creation softwares that i have stumbled upon. Also, anyone familiar with the Slenderman's Shadow series should know that this engine was used to create those maps, so you know that it's pretty damn powerful!
First, I'm more into modding than "real" game creation, but I gave this fella a try.
I've only tried it for a month, but what I've seen is amazing, really. While the programming is not really well optimized, the graphics' side of the product is really breathtaking for a mere 30$ engine.
The engine supports normal and emissive mapping, specular highlights but also High Dynamic Range, ragdoll physics, dynamic projected shadows & lighthing, animated textures, cubemapping, reflective sufaces such as water, mirror and floors.
A great engine for beginners, the only thing i don't like is that the engine is litterally plagued by tons of content, which have to be paid. It may be not a great issue if you have some knowledge into 3D and texturing work, but it's very annoying to know that some of the features I've enunciated have to be paid ( they are shaders ).
Because of this, I cannot give it more than 8
