RB Whitaker, others,
I've successfully followed you tutorials with the goal of replacing OpenTK with Monogame for my application.
However, I've noticed that the .xnb files which the XNA Content project generates are huge in comparison to the original .png files (sometimes more then 10x the original size!). So far, I've been unable to figure out how to, f.e. add compression options or how to reduce the colordepth of the textures, in order to reduce the size somewhat.
In your method, is it possible to apply some form of compression or alter the properties of the generated XNB's in any other way?
