The game should be playable on mobile phones. It would appeal to the broadest range of users if the theme wasn't based on cryptocurrencies just the in-game credits.
Agreed. In-game currency wouldn't have to be called NXT. In honor of CfB, we could call them 'Roobles' and they could look like rubies.
Also, I dont see why to limit to a single game. Games are BIG! I suggest keeping track of all the ideas and start with the fastest to get working. Doing something simple is a great learning experience. Then the second game becomes more ambitious, etc.

P.S. Please keep track of all the donations that come in for this, I have a feeling the total will become quite large, especially if you offer ingame Vorpal swords to big donors
