NQ should create 5 tiers of subscription
tier 1: free
tier 2: 10$
tier 3: 20$
tier 4: 30$
tier 5: 50$
These will then correlate to the tier of ore / component that your account is allowed to use
by doing this NQ can more easily stabilize their finances and this would allow more people to access the game
Also the free tier would mean theres no need for a demo server and the population of the main server would be far higher and seem far more alive
