So Zoom, i've amended your table to include the amount of NIC that will be generated in the game by someone getting the amount of tokens required for each of the items in the shop. Mission income is derived from a level 6 mission earning you 60m for 600 tokens. Lower level missions generate less money for less tokens but the curve is very similar.
Remember to be a NIC sink the cost of the item must exceed the amount of money generated in getting the tokens.
Tokens NIC Mission income
T2+ module 10,000 10,000,000 1 billion
T4+ module 20,000 50,000,000 2 billion
Black robot 100,000 250,000,000 10 billion
Now arguably if there is something you want a glut on the market of it is not NIC, it is tokens. The less NIC in the game the more valuable it is and the higher the market activity to get it. The more tokens are in the game the more they are used for othe things such as ammo and whatever those new bacons are.
What I suggest is:
Tokens NIC
T2+ module 100 15m
T4+ module 5,000 500m
Black robot 50,000 7.5 billion
That reduces the number of missions needed for a black heavy but increases the NIC. Doing level 6 missions on Beta will require about 125 mission to earn that amount of NIC. If you did that many missions you would have 75000 tokens causing a token glut in the market and a definite NIC sink.
Just to be clear why a token glut is a good thing - it makes people who have those tokens find NIC from some place other than missions so that they can use it. This causes market activity as people sell stuff to get the NIC needed to use the tokens.
Proverbs 23:20-21 warns us, “Do not join those who drink too much wine or gorge themselves on meat, for drunkards and gluttons become poor, and drowsiness clothes them in rags."
