Earlier quoted context omitted.
You know, we've considered it and we've been approached by a couple of publishers in the "hyper casual" space to go the route of free-but-with-IAPs. First the terms of industry-standard contracts are onerous. And second...well, I personally love casual games. And I never minded paying a reasonable amount for games I play. And then there are games like Two Dots that I really, really liked but the endless monetization…
Congrats on the release! I can only say anecdotally from my own experience, but the games we had listed for a price got 1% or less of the downloads of the same game after we made it free. People complain about free with IAP, but the $ shows otherwise.
If you want to do this as a business, free with IAP is a must.
