Yeah, I'm not seeing where he says that there is some sort of hard-coded level limit of 100.

I'm not sure that you could actually create a hard limit of 100. You're either limited by the spaces in a field (in which case the limit would be 99 or 999, not 100) or some form of binary or other calculation (in which case I could understand a level limit of 128, but not 100).

Actually, now that I think of it, a database could put 100 values into a two-space field, since computers can start counting from zero (0-to-99 is 100 values, the game could display the value +1). It just seems incredibly short-sighted to have limited a field to two spaces instead of three in a level-based game where you planned to get to 100.
