Seriously. I was appalled to not find something like this on the XNA homepage where I can just go and grab some pre-made components (and not the silly sample ones) slap them together and have a game.
It wouldn't be hard - in today's gaming world any game is just a conglomeration of concepts from games before it. Need a FPS? Throw a map object with a fps camera object, some weapons with cool models and stuff together, with a custom ruleset (also pre-programmed) and BOOM. Maybe add in a HDR control, and a gunblade weapon too.
PROGRAMMING == NONE.
But FUCK. I can't make my drag-and-drop MMORPG unless I have a place to download the components for it. Seriously.
GET WORKING PEOPLE.
(oh, and can I get credit for the initial component-library-site idea when you make it? :3)
