http://www.wihlidal.ca will be coming back online once I finish overhauling the content on it and bring everything up to date.
On a somewhat related side note, I am playing around with the idea of writing another book. Everything from a revision of Game Engine Toolset Development for .NET 3.5 and XNA instead of MDX, all the way up to something totally different.
Any ideas? What would you like to read about these days that is related to game development, C#, graphics, optimization, tools, etc.. ?
