Those numbers are comparing 5e24 phb vs 5e14 phb. That's the comparison I'm interested in, but the numbers don't exist yet to properly compare them. If we had three years of 5e14 sales vs three years of 5e24 sales, I'd be more comfortable ... As it is, I couldn't make a fair comparison- but speculation based on hype math isn't something I'm interested in.Feel free to suggest other ways to measure D&D's success. I'm sure there are some, but selling more copies of the PHB in less than three months than the previous version (which, in turn, sold substantially better than all previous edition PHBs) sold in three years seems like a reasonable starting point for assessing how well D&D is going.
