Is there a reason why max cash is kept so low? I can hit that number without cheating... Just sell a few ufos you recovered...
Displaying so many zeros is also unhelpful. Perhaps displaying it using two variables might be more helpful...
Like "1,000,000 K" for billion
or "1,000,000 M" for trillion
No one will care about the last 3 digits if they have more than a billion in cash...
No one will care about the last 6 digits if they have more than a trillion in cash...
Various SI letters:
