There's so much more I left out! One of the main things is currency.
dCrops has an inflationary currency, with a clear and predictable plan to create a reward system based on this currency. Inflation, in this case, is a 'necessary evil' to have a reward system. There is no glass cealing. Players can value the game at whatever they want because of the expectation of rewards/reinvestment/increasing players.
A well-managed inflationary currency, with the future laid out in a clear way is all-important to these games!
Again, crypto brewmaster has no such plan in place. Not transparency in regard to the most important aspects! No clue how to create value for the casual player. I fully expect players to get surprise-screwed at the most perfect time (for them). That is, realizing their currency/reward management won't work for the long term.
The key is transparency and predictablity. This brings the big investors. The more 'immutable' you can make your reward system, the better. And yes, this invovles laying out modifications for increased player base.
