Upgrades of Omega services are more expensive, instead of upgrades I buy more level 1 services. (Though I had to remove population boosters to have enough room for reorganisations.)
Omega Power Plant (upgradeable to level 10):
My costs to get level3 (capacity 2025) = 10,000+15,000+20,000=45,000 Neo$
If I buy 3x Level 1, my total capacity is 2025 too, my total costs are 30,000 Neo$ only. I saved 15,000 Neo$.
Guess how many Simoleons and NeoSimoleons I spent before the math clicked … … yes, right, I spent all my Simoleons on upgrades.
Math! I should use it more in my life, math makes life less expensive and it makes implementation of Services 2.0 less expensive too (as long as the rules do not change again).
