Hi Guys!
Reading this article about the making of the game http://positech.co.uk/gratuitousspacebattles/makingofgsb.html I get that GSB is built on DirectX. I’ve just downloaded the OSX version and since I’m a curious developer… I wonder if you can give us some more information about the porting to OpenGL 
Currently I’m keen on OpenGL and I can’t hide that a technical article about a 2d Engine written by the author of a REAL VideoGame would be an awesome source of inspiration 
Thank youuu!
