This is a Guardien(Hero) of the temple(only one stage which I'll post here next as soon as I get some time to make it).
Game Engine is a tool that allows you to test game physics using your own computer's PhysiX engine. There are readymade engines if you go to Gamedev.net but you can make one on your own if you know C++ openGL and directX.
Game Builder is a tool that allows you to drag these characters and drop them in the prospective and program them or impliment events such as Left mouse click and rotate or it can be W, A, D / Uparrow, Leftarrow, Rightarrow which can be assigned to the model to move Forward, Left, Right. You can also make a tool in the game builder which'll allow you to make physics. A Unreal Tournament Engine would be the wide example.
Map Editors are no longer provided by games but they used to be. A person can create his own model impliment it and use Map editor. Map Editor are simple. They allow you to make and edit maps.
There is no small intro to the game that I will be posting here as soon as I am done my college and will start working on this piece. But I have further plans then this. This one is just a test run to see how things will work and it'll allow me to get used to the stuff, what are peoples' like and dislike about my game or my style of games. Once you are finally done with testing you can finally code them in creating relations between the introduction cinematic to first level, and it can be extended to many levels.
