Dont forget if your new to the world of game design and programming, then you seriously need to maybe try "Pong" or "Space Invaders" before tackling a game project like this. I been in school (westwood) game design for 1yr 4 months, and guess what, I still wouldnt try anything like that. Multiplayer = high server cost ! Im not being mean, as I highly encourage you to pursue your idea, and complete it. I will be the first to play it! Good luck
