My Narva scenario's paid sales are at the same level, but since I left it as PWYW, it's about 80% of that. Both Rüdiaria Awakening and the Missing Baroness have reached 40+ sales, so i hope that they also hit copper best seller status by summer…
Looking at my sales, there is a core of 20-30 or so purchasers who buy adventures quite reliably, the rest kind of trickles in, with bumps upon release of new material (though with PWYW, it doesn't mean €£$¥).
Secrets of the Empire (1.5 years since published) - has sold 104 copies
Of Magic Condensed into Shape (22 days since published) - has sold 65 copies
Elder Magi, Volume 1: Audrey de Verditius (2 days since published) - has sold 11 copies
It looks, for now, like the Elder Magi is the worst selling item, so far. It certainly sold worse than I had hoped. But I am committed to the series, and will continue making them.
