I participated at XNA Pizza Night yesterday, and when there with the 4day game I made. We won!!… well at least some Pizza 
.
But it was really fun, and there where some amazing games there, including the Night’s Winner Vizati, who took home a xbox 360.
I recently found that C# is the best thing to learn.
1 – Microsoft supports it, that means, best documentation, best community, best software for development, best software.
2 – Multi-Platform! Runs on Windows, Linux, Mac, and others. ( Mono ).
3 – If you want to make apps, make them. If you prefer games, make them too, with XNA!!.
So basically. I’ve been digging the msdn library and learning the language, and Windows Forms. I’m getting pretty good now. This will help me make better games with XNA too, so, its win win… 
I highly recommend.

Well, I am late, because I didn’t had the chance to work sunday, because I play soccer, so I finished it today. I know it doesn’t count but I’m posting the game here for you to try it and criticize positively and negatively if you want, so I can make better games.

This time I used XNA from Microsoft, but I will remake it with SFML and C++… Because I don’t know what dependencies are needed with the game. The images have the background around them, because I don’t know (after googling for it) how to mask a color in XNA, the XNA framework might be really good, but as for documentation it surely sucks. That is why I want to remake it with SFML/C++, and that way I can port it to Linux, sorry Mac users, I can’t compile for Macs..
Also, I don’t know with dependencies to deliver with the Exe so I recorded a video for you to see the final game. And I am giving the source code for curious people.
