Exactly, like I said, you seldom have to roll your own.
So how do you learn? Of course, there are many full featured engines out there, that doesn't mean one shouldn't learn at least partly how they work.

Kevin Your best bet would be the App Hub forums for XNA at http://forums.create.msdn.com/forums/[^] Stack Overflow also provide pretty good XNA support. Be prepared for a lot of frustration getting started......

Pick a bitmap of a world-map. Give each country a unique color. When the user clicks on the bitmap, request the color of the pixel that has been clicked. Lookup in the dictionary which country the color was mapped to.

That might be a very good or a terrible solution, depending on the scale of the map ;) I would add that you would probably use two bitmaps: one to display a nice looking map, and one with flat colors to do the hit-testing.

Do you all guys have too much memory and don't know what to do with it?
At least artificial intelligence already is superior to natural stupidity
My PC has 16GB yes ;p I've started my post by saying this using bitmaps could be a terrible idea, it all depends on the project (design, hardware target, etc...).

Who does not at least have an i7, 16 GB and a GTX 580? :)

Me, my graphic card is rather old ;p The Xbox360 and Windows Phones too (possible targets for XNA).

Uhm, you do know that that means that he must set up custom data structures and custom shaders?

I think we might have a language issue here. You seem to be saying he can use the same data structures as those "ou find in a pixel shader or a vertex shader" and perform the hit test on the GPU, right?

1 Gb physical, and some swap-space. A 320x200 bitmap, scaled to 640x400 would still look "decent". Not much wasted space if you only use a few colours. As for practicality; you might want to use two worldmaps, one where you can select a continent, then a version where you select the country. That way you limit the colours you need :) Next!
