First, If you haven't already, download GameMaker at YoYoGames.
Then, follow the intructions when you start the program, that will take you step by step into buying the product.
GameMaker Pro is the upgraded edition of GameMaker Lite. In the new version there are many more things you can do and many more kinds of games you are able to make.
You can't really get the pro version anymore; game maker 8 is out on yoyogames.com. The latest version of the Gamemaker series is 8. They have discontinues support for gamemaker 7.

$19.99 or £19.99. you can't get 7.0 anymore and 8.0 is $25.00 USD
download gmk 8 and go to youtube and search.(gmk8 is better!)
Seneca Crane was head gamemaker.
it is easy to make a game on 3d gamemaker
It was never mentioned who the first ever head gamemaker was, but for the 72nd, 73rd and 74th the head gamemaker was Seneca Crane. For the 75th games Plutarch Heavensbee is the head gamemaker.
GameMaker isn't meant for making 3D games, but it is worth the money you pay to register. I hear there is a better 3D game-making program called Roket3D.
It is a great program. I imagine that the recently-released gamemaker 8.0 is ever better. You can download it at yoyogames.com
