I'm speaking on experience here. I have looked on the net for 3D game creation software before, and most of what you'll find is mostly just 3D game engines that require that YOU do all of the programming in C++, or VC++. I dabbled in both and unless your good in trig, it's really not worth the manhours it would take to create a game from scratch.

Now, when I came across 3D gamestudio, I was amazed. No other product out there can match it in it's ease of use. You don't even have to program unless you want to. And even at that, WDL is pretty easy to pickup.

The easiest game to make would be a simple 3D shooter (like half-life or quake) to start out with because there are allot of functions already written for them. Such as weapons, charactor movement, etc., So you could just put the game together in one afternoon. Check out the 3D gamestudio home page and read up on it. It's awesome!!!
