I was replaying SC2K(dos) recently and it is much harder than I expected. Usually these city games are fairly easy chill affairs. On a 1900 hard(max bond) start the only way I found to succeed(marked when I payed off all bonds) was to pause(to avoid early bond repayment losses), use all your money to setup the perfect layout for the next 40 years. Then wait in debt(can't build anything) for 40 years while hopefully your city profit grows past the bond interest amount and you are able to slowly claw yourself out of the red. Then immediately start saving for the replacement power plant as your original one will explode soon. I was not making a comfortable profit until about 1960. And this was after many failed cities, can't fix anything when you can't build anything.

Not sure to what extent you're looking for a reboot to be representative of the original, but I've been following the development of this indie spiritual successor for some time: https://store.steampowered.com/app/2287430/Metropolis_1998/

SC4K - The original binaries run at 1080p on modern hardware with excellent performance and gameplay with a few command line tweaks.

With respect to SC3K being great still, I would run it but I haven't been able to get some performance issues ironed out.

Worst might be SC2K for N64.

Neat concept would a game to import cities into a GTA-like engine.

i first played 2000 when it was bundled with my family's windows 95 pc, and was sad to learn that gog/steam sell the inferior dos variant. but, yes, 2000 was just right.
