A little internet investigation locates the advert in question -

Isn't this a tragic tale? Particularly poignant is the cruel way the girl with the blond pony tale rejects Maxy. No doubt Maxy organised the whole games night merely as an excuse to invite her over. But when she finds out he only has inferior games, she storms out, crushing him with the cutting phrase 'Later baby.'
Young Maxy would undoubtedly be devastated. Later in life he'd need therapy for his romantic failures. Even then he'd never really be comfortable around girls.
The blond haired girl does appear again in the last panel. But by then it's obvious she only likes Maxy for his games. You can tell from her body language that's she's not really interested in him. Probably by this time she's secretly dating the lead guitarist in the local speed-metal band.
What really sticks in my mind about this advert is not just the way Maxy is spurned by the woman he loves, it's that the game he's mocked for owning is called 'Manholes of Venus.' At the time, nothing struck me as odd about that name. But now I think about it, it's a very strange title for a kids game. Manholes of Venus? Did whoever wrote the advert realise the various interpretations you could put on that phrase? It sounds like something written by Petronius for the Emperor Nero, detailing events at their latest orgy. I really want to play Manholes of Venus.
At the time, at the start of the 80s, an Atari games console would have seemed to me like an unobtainable luxury item. I never knew anyone who owned one. But I recently bought myself a PS3. Ha. Take that, writing career.
