I don’t see how your first paragraph contradicts anything I said, so I’m confused by your use of “actually”. You can call old games “classic”, although I’m not sure any of them are old enough to be called “antique”. Maybe an old Pong home machine or something. Those words all largely mean the same thing.
I would say “retro style” is redundant. Retro is always referring to the style. Looking back and taking styles from the past is what retro means. Like modern bell-bottom jeans, or cars like the 11th generation Thunderbird which looks more like the original that any previous models.
The Wikipedia article uses the word to describe it.
This was the last year [4th generation] for the convertible until the “retro” models of 2002–05.
Ah, no, I was definitely saying that, and I still think “retro” is definitely incorrect. It was just confused that your first reply didn’t actually contradict me. I don’t mind at all that you think I’m wrong, but I’m not convinced. When everyone else but gamers seem to understand the difference between retro and classic/vintage/antique, it’s the gamers using it wrong.
