It all depends on what values you're willing to leave unrepresentable.

(Bearing in mind that the set of operations that you can accurately support in your number system also depends on the set of representable values.)

If you don't really care you can go arbitrarily high.

Very true, but in all fairness the proposed solution of using Turing machines is pretty reasonable. I think the title is a play on Scott Aaronson's "largest number" game.
