There are two issues with it (in my opinion):
1. There are several mistakes in it.
- C is not an OO language.
- openGL and LWJGL are not engines, but libraries that allow you to draw to screen. Engines are more complex pieces of code that hide a lot of computation and/or storage from the programmer to allow easier programming towards a more limited set of goals. Take a physics engine for example. It hides al the math and allows the programmer to just specify the objects and some relations and parameters. This makes simulating physic easier, but the engine is useless for anything else than that. openGL and LWJGL try to give you as much control over the computations as possible. The border between a library and engine can be grey at times, but openGL and LWJGL are defnitely libraries.
2. What would be the reason to read this document?
It could be me, but anything described in the document is either obvious or found in any tutorial that even remotely deal with the subjects.
Instead of making the first few lines look like a f*cking flyer found at gamescon, try to describe for what audiance the document is meant. Currently the first lines give the impression the document belongs in a magazine, read by anyone with a remote interest in games. Is this really your target audiance? The rest of the document seems to focus on people that already made the decision to make a game.
If you force yourself to describe target audiance in the first few lines, the reader knows if the document is usefull to him/her and you know better what to tell/leave out.
Note: No offense, but I did not comment because I would like to see an improved version, but getting feedback may cause your writing of documents to improve, a usefull skill.
You are allowed to find my criticism rude, but at least I try to be constructive.
I hope I did not destroy too much entousiasm and you do/make/program something awsome in the future.
