All Japan GT Championship (GT3)?
We have a winner! Explanation:
"Is that what I think it is? It is! What the.. ah, I see what you did there, PD, that's a genuine easter egg!"
You'll understand it in a moment.
"The successor to Oxyacetylene is related to this"
+
In what way is Oxyacetylene and Gran Turismo connected?
Oxyaxetylene is (among others
) a song by Cubanate, which was used on the language selection screen of the original Gran Turismo. Particularly the language selection screen part is important.
"Less random guessing, more thinking = less wrong answer, more bingo."
I wanted you to think more about the riddle
"Where does Oxyacetylene and Gran Turismo mix? What could that have to do with a successor, which has something to do with an easter egg related to a GT event?"
Oxyacetylene and Gran Turismo mix at the language selection screen in GT1. The successor would be the language selection screen in GT2.
"Opel or Vauxhall?"
On the PAL version of GT/GT2, selecting English language would "open" the Vauxhall dealers, whereas German would open the Opel dealers. Where do you select language?
"You'll need to use your
imagenation to find the answer"
Double-pun:
Image: it is related to an image
Nation: the event is (sorta) national
Confused? There's a little more to it:
The language selection screen in GT2 featured an image of several mainly/entirely japanese vehicles parked in a pattern. This exact image can be seen on the very right side of the "banner" for the All Japan GT Championship in GT3 (and GT3 only)
