Aha, Sky Attack I think. Also my fave, though only cause my mate had it for Christmas (guess 81/82) and we found it hidden by his parents. We'd given it a good caning by the time Christmas came round haha.
I had the blue one , ummm Planet Zeon I think, which was stupid hard and 3D Skyfighters which was cool. My brother got the white car one.
Ahh good times
although my actual first electronic game was umm some black car thing. More mechanical really. Errr, lemm think.
my older cousin had a speccy at the time. He said once you get a computer, you don't want any sad hand-held stuff. He was right lol
