Even on hard difficulty levels I soon get a lot of money due to various reasons.
But there is a time when money isnt really useful anymore. I myself have supported prosopals such as
digging underground (to further extend a main base) or giving "research grants" to research projects to
stimulate the speed of research.
But actually I think the one thing that could be implemented super quick would be this:
- Money as a way to hire additional people.
In reallife you often see that people will accept the better paid offer. And research is in no way
different from that. I'd propose that you can hire ie researchers even if "none are available" if
you simply offer a lot more money. Or maybe make it per project, I'd really love to have ways to
use the extra money i have, and research is the most important aspect for me (as the early
weapons kinda suck IMO especially if the aliens come with their long range weapons ...)
