DLC (Down Loadable Content)

DLC is an awesome thing, it makes so the life-span of your game is expanded for how ever you want! DLC is something I realy want in DOWN-FALL (my game) or games I will make in the future. I was wondering if anyone new HOW to make a server for use with DLC and if it costs anything, how to impliment it in DOWN-FALL and how to make it so they have to pay (some of the bigger DLC will be like 50 cents-to $1) I know I've been asking ALOT of question in the short time I've been on these forums, but I want my indie game debut to be as awesome as possiable. I want people to say "holy f***, how did a 14 year old make that?!"

It's good to think about this, but I think these are details which don't need any priority right now.

The biggest first step is: making a fun game.

I know, but I asked this in case I have time to implement this into my current game or my future games,
