No, sorry, it's not something I am willing to endorse. It's not a question of games vs. books, though. It's just taking SVGs produced by my generators and selling them more or less "as is" doesn't sound like a fair commercial use of free tools (unlike creating illustration for original texts, for example).

Please note that I strongly disapprove abusing this "license" by selling generated maps.
