I have several years of experience in the development of mmorpg games.
But there are some things I am not convinced:
1) Using the Arbitrary Messages to store the player, that means one NXT by every time you play? is unfeasible.
2) Asset Exchange to trade items? would be easier if I had an own exchange system with NPC trading.
3) Not meant as mining work.
I have not seen a concept of how the game should look. Points of the expectations of the idea are, in my opinion, very little practical.

1) AMs will only be used to store misc. data if the player wants to export/import data. Most likely (with the current min. fee) we'll keep most data on the server. Only items will be tied to the asset exchange.
2) Imo, interfacing directly with the AE provides a very unique link between the economies. Plus, all asset trading, distribution, etc. is public. Assets can even be traded even if you are not in-game, as long as the asset is in your account.
3) Not sure what you mean here.
You're welcome to contribute your ideas! We're still very much looking for talented devs
