Make Your Own Xbox 360 Games!
Microsoft has recently released XNA Game Studio Express, an application which makes your pc and Xbox into a development tool currently for making Windows based games but with another release or so, it will be able to convert that code to play on the Xbox 360. I'm excited about this product because I think after spending some time with Visual C# that I could actually make something (very small) that might be fun to play. I need to make some time in my busy busy schedule to play with this thing some more. Fun!
