You want to raise some dev funds for this?

PRE SELL some Assets, IE Vorpal Swords (whatever these are..) Shield of NX, AE Armor, for example.

Say you make a whole set of 1000NXT armor and items,  these items would have a value of 1500NXT once the game starts. Pre investors could put theirs up for sale, and therefore individual investors could make a profit and help the game get started
