You're able to make almost ANYTHING. RPGs, 3D mazes, actions, puzzles, Smash Bros (more basic version of it of course)... you name it. However it does require constant learning. Beginners should start with text-based games or just simpler things like moving a character around, and then build on your knowledge base. Or, you can just download and play people's games. Playing is learning too!

Ah, silly me, I see you already bought it and started asking questions. Well my comment is for people who're still on the fence then

Directed at L. : I very much appreciate your reply. I am considering getting this and your response was helpful to me so, I write this comment to let you know that it did not fall on deaf ears. All I ask further is this game okay for someone with zero experience, i.e. moi?
