Commented before I read this. lol.
Similar outlook.

The only thing we disagree is that the game wouldnt have a way to sustain development if right now all rewards go into LP. Eventually they should but as you can see the first sale only got about 20k USD into the development of the game. So he either does a sale every few quarters or so or the delegation and other rewards stay.
The HP delegation rewards arent really rewards due to high inflation. Theyre giving up a part of your HP APR to help fund the game. Its not really profitable at all. The logic as I see it is that its preferable to give up your HP APR over the course of the year than spend money right away.
