Unreal Engine 3 - FREE

[Hedayet]

This is what they says: "UDK is Unreal Engine 3 – the complete professional development framework. All the tools you need to create great games, advanced visualizations and detailed 3D simulations. The best tools in the industry are in your hands."

 

I did not get enough time to look through the detail features, but its "Unreal Engine", one of the best out there.

for commercial use there is a very reasonable and transparent pricing:

 

Internal Use: 2.500 US $ per developer seat per year

Publishing: 25% royalties for revenues above 5000 US $

Internal Use may stack with publishing thus: per seat per year plus royalties
