As far as slowing down the exponential growth at the start of the game, many of the elements put in are doing their job:
- lower demand the first year
- higher slot fees
- no slot purchases while in negative cash
- lower "visible" demand while low CI/RI - well this one is kind of iffy whether it works
There is one huge hole left out, which I would call LH exploit. It is still way too easy to get LH aircraft, fly to LHR and get great LFs, way higher than even flying SH.
I don;t see this as very realistic. LH should be a lot more sensitive to RI, especially CI. Making LH LFs more sensitive to CI would close off this early game exploit...
