Hacking rules.ini for C&C: Red-Alert!

Game was too frustrating, but hey changing this easy to understand rules.ini file completely changes it to my favour! Also you could do hilarious things like an attack dog launching an artillery as its primary weapon. It taught me how to debug and roll-changes back when the game crashed with the dreaded "Internal game error" message.

But seriously, it was my first introduction to "programming" and then got me into QBasic via "Complete Idiots Guide to Programming" which I borrowed from the local library. I was also super into Aerospace and this book [1] also from the local library gave me background into computer hardware.

I really like this book, I first read it 12 years ago while still in High-School. Got me hooked on computers :)
