I upgraded the finance centre fairly early, so it probably paid off, although I can't say for certain that I made much more than 50,000 in cash to make it worthwhile.

Do you have any useful or experimental strategies to share?

Also, I have less than 3 hours to sleep now thanks to this game. Gnaw-some.
