With 3DRad currently in its death throes, I've decided I need to broaden my horizons. So I've downloaded the free Unreal Development KIt (UDK) and bought myself two Kindle books ("Unreal Development Kit Game Programming with UnrealScipt: Beginner's Guide" and "Unreal Development Kit Game Design Cookbook").
 I'm going to lock myself away for two weeks, whilst I conduct myself an intensive course to get to grips with the basics.
I like the idea of having all the design tools in one bag and being able to apply OOP (Object Orientated Programming) based script to all objects. 
I'm thinking of using UDK to develop my "Hometown Walkthrough" project. 
Oddity is still my first choice for my physics-based  projects. 

Well within my deadline!

Details and a free demo download can be found on my new MeccanoRAMA page.
