Last night I downloaded XNA Game Studio Express...
Just for fun, just to play with.
During an hour I ran through the tutorials and then went on in my own direction for an additional hour (or two...) and ended up rotating a space ship in all axis.
And all of a sudden I remembered why I started programming for more than 25 year ago, because this was probably the funnies programming experience I have had for a long time.
I will probably not become a game programmer but on the other hand I will probably play around with XNA Game Studio Express some more... much more. Just for the fun of it.
