First home computer was a Commodore 16 which I was overjoyed to come down to on Xmas morning! I found out years later that my Dad had been up all night "testing" it and was knackered for the whole of Xmas day as a result. He became addicted to a tough as hell game called "Fingers Malone" and eventually completed it. Something I never even came close to doing!
The games I remember playing most were "Bandits at Zero", "Prospector Pete" and a very basic football game I cant remember the name of.
After that between me and my brothers we had a Spectrum 48k, Spectrum 128k, Commodore 64, SNES, Mega Drive, Amiga 500+, a couple of PCs, PS1, PS2 and now a PS3.
What I loved most about the early Commodore and Spectrum days was that you could nip down to the shops and pick up a game from £1.99 or £2.99. There were loads to choose from and the pictures on the cover made them all look fucking amazing, even though they were crap most of the time. You could even borrow games from the local Library!
If you had shown me a game like "Skyrim" when I was playing my Commodore 16 I would have literally jizzed in my pants. Then you would have been burned at the stake as a witch.
