and a differant one where sega beat out nintendo.
I don't know are the other dimensions/universes, but I think altough our universe is limitless there is limit to how far matter has spread.

Do you mean interdimensional?
I don't know.
Maybe, maybe not.

If there are diffenrent universes and dimensions, and our universe is endless in true sense (as in also the matter has spread endlessly), then still... maybe.
