Well, my favourite video game of all time is probably Pacman - it was in the foyer of the local sports centre where I attended a roller skating club when I was about 10. I was completely addicted to it, and had to go on it every time I went there. And it was only 10p a go, so good value!
My second favourite video game was a game called Donkey Kong JR, well, I think that was the name, not completely sure. It was one of the first Mario games, I believe. It was around the time of the Pacman addiction - the early to mid eighties.
Funny you should ask this question today, as this week there is a retro gaming exhibition in the Forum, in Norwich. I went in there, mainly because my son wanted to see it, and both of these games were there. It was quite nostalgic, though now that I have grown up somewhat I don't really like video games at all.
