Uhm… I don’t know. I mean, in PHP the first P stands for “PHP” itself.
So the protocol could have been called also QHP, or FHP, or XXHP or whatever. It would have made sense anyway.
But in our case, the M in MARS doesnt’ stand for “MARS” (the acronym). It stands for Mars (the planet). If it was called VARS or JARS, it wouldn’t have made sense (except if we were on Venus or Jupiter, actually).
And please do note tht MARS is also an acrostic, not only an acronym.
Please, @RonGilbert, DO read the unwritten text. This whole thread means only one thing: make a new game!
