This game is great this is one of the best recent tycoon concepts (up there with game dev tycoon imo).
One point of criticism, even on Very Hard if you immediately license the lithography and contract the foundry services from TI you can immediately jump to a few billion.
The licensing and contracts together is overpowered, perhaps a business relationship mechanic or having to put collateral on the contracts etc. would be a better way? Just so you cant become a billionaire after 60 seconds. Or maybe make the contractee pay a fee for unused capacity.
