Yes, that's exactly on point. The other half of the meaning relates to the quotes - it's not the videogame that's the "Mother of All Games" - it's war itself (meant cynically, of course). People in power scorching the earth is one of the oldest games.
The press, I distinctly recall, liked to call it. "The mother of all guns" However I am unable to find a citation in the 30 seconds I spent looking for it.
Your side poster red369's more likely correct, as "the mother of all battles" was quite a well-known meme during Gulf War I - especially given the MOAB was designed in the early 00s, which is a while after this game's release.
