I re-installed 3 game engines today:

Gizmo SDK
Panda 3D
Irrlicht

A few years back I tested two of them, Gizmo SDK and Irrlicht, and found them to suit me very well. They are not a “Point-and-click” type, you have to know programming to use them. But I’m not a VisualBasic type of programmer, so for me, being a C/C++ guy, this was just perfect.

If you have been looking into game engines and programming, you surely know Irrlicht, but what the heck is “Gizmo SDK”???

I can tell you it is a highly professional development kit released to the public (again), free for personal use. You could say it is a spin-off from Saab Training System AB, in Sweden. It is living here: http://www.gizmosdk.com/

The 3rd one, Panda 3D, scared me a bit in the beginning, I got the impression that it was more like a tool for hobbyists, more like the VisualBasic school of programming. After returning to it yesterday, I changed my mind. As they say in the manual:

To successfully use Panda3D, you must be a skilled programmer. If you do not know what an “API” is, or if you don’t know what a “tree” is, you will probably find Panda3D overwhelming. This is no point-and-click game-maker: this is a tool for professionals.

I changed my mind and installed it.

I’m also looking into delta3D, but need more time.
