One is about doing a return to castle of wolfstein clone, including network code for Novell networks, the other a 3D engine in C++ for a space shooter.
Is it "Tricks of the Game-Programming Gurus" (https://www.amazon.com/Tricks-Game-Programming-Gurus-Andre-L...)?
> a 3D engine in C++ for a space shooter
The other seems to be "Building a 3D Game Engine in C++" (https://www.amazon.co.uk/Building-3D-Game-Engine-C/dp/047112...).
It's amazing to see old gamedev books :)
