I am partial to "relative to car orientation" vs. "relative to screen orientation." At least to me it is explicit. "Relative" does not really qualify to what it is relative.
Fair enough. Reminds me of an old joke: The two hardest problems in Computer Science are cache invalidation, naming things, and off-by-one errors.
Why would people complain so loudly, enough to cause Mattel to react, to make the game harder to play in the general case? It seems much more plausible that the change would have been the other way around.
Maybe the change happened between the test marketing and the final production run?
I need to look at the delta between the two versions a little more closely. I recall thinking that one of them looked more elegant than the other. I vaguely recall thinking the version without the Easter egg actually looked more ham-fisted in the part that handled the steering dispatch, but honestly I can't back that up right now.
I've seen an even more inexplicable change in Las Vegas Poker and Blackjack. Between the two versions of the ROM, a two instruction sequence changed to a different two instruction sequence that's exactly the same size, takes exactly the same number of cycles, and does exactly the same thing. WTF? That's not a running change... that's a running stay-the-same! Or something.
