We all thought it was portable back in the day - we all took them everywhere with us, so maybe it was - but really, the Game Boy wasn't exactly pocket-sized... just... smaller.
Smaller it might have been, but it absolutely wasn't lacking when it came to great games - many of which we'd totally forgotten about before digging about in our attic for this one.
Unfortunately part of the research did involve disqualifying any of those 100-in-one cartridges we picked up while on holiday in Spain. Darn.
