Holger Bech Nielsen, one of the founders of string theory, has apparantly just played some sort of game between different potential dimensions for space-time and reached the conclusion that D4 wins in a natural way:

Could someone please try to explain the gist of this game and the broader reasoning behind it in laymans terms, and perhaps answer the following related questions: Does anyone pay notice to this developing research? Does the result have implications beyond the Standard Model, e.g. for string theory?
