Ye exactly what i said !!....If you read the first one it says....Retro is a culturally outdated or aged style, trend, mode, or fashion, from the overall postmodern past, that has since that time become functionally or superficially the norm once again.....
Then it states.....It generally implies a vintage of at least 15 or 20 years.
Wiki is using the word vintage as a year.......like grapes.....what its saying is retro has a vintage of 20 years.....not that it is vintage gaming. Elvis presley has a vintage of over 20 years but its still rock n roll
Like you said though...if i said its ancient doesnt mean its its egyption or anything im would be just using the phrase to make it sound old so it doesnt really matter he can make his choice of wording
