This is the first game I ever remember playing on my dad's old pre-8086 home computer. It was called "Alley Cat" (circa 1982-1983ish)
I also remember being a big fan of Zaxxon on that same computer
Later when we got our blazing fast 386 that ran Windows 3.0 I was able to run the first FPS shooter ever - Catacomb Abyss! It was also the first game I ever remember pirating from a local BBS site.
Followed soon with Wolfenstein 3D
And I remember installing the very first edition of Alone In The Dark on a 486 without a CD-Rom drive. It took at least a dozen floppy disks circa 1992
