He shouldnt focus on Leveldesign atm.
He should do a clean programmcode and THEN well looking graphics.

Block testmaps are suitable to test programmcode and do not eat to much time to get to a playable version.

I do not care about leveldesign guys, I need to improve my programming skills, but not all guys understand that, I'm learning from snippets and scripts made by other programmers, and after learning them, I'm trying to make something on my own, I think thats the good way to start... I was wondering about making my project about WWII, I want to see what you think about that guys? What better, to make game about WWII or about war in Iraq? Please reply, I need your advices.

I think it would be better, if you make a mordern war game.

My opinion is a modern war game. But avoid Iraq, or any other "real" war.
You are potentially upsetting potential buyers if it is a contravertial issue.

WWII games are getting a bit old-school. But the advantage here is not so
many games in the market to compete wirh...

Definitly modern war.
But I agree with EvilSOB, avoid real wars; You can aim on realism, but create a fictional conflict.

OK, I'll try to make it modern war, I just have some ideas that will make WWII war multiplayer game much better, than other WWII multiplayer games now. I haven't seen that ideas in any game. So that what I was thinking about making that ideas in my project, but OK I'll now do that I'll make modern game, not exactly in Iraq, but some were in Asia. Thank you guys.
