I have been playing with XNA for a bit and I am very impressed with the SDK, IDE and ease of use. The best thing I like is the starter kit game that is included with the product. I have always liked MS development tools and the XNA C# based kit follows the high level of standard MS puts into their tooling.

The great thing is, when you create the SpaceWar starter kit you can use this as a learning application by looking at the source and of course debugging it – excellent for beginners. I have already started playing around with my own objects – created in TrueSpace 6 – with the SDK. I honestly can not believe how easy it is.
