Unity has crashed on me three times now. And that's just while gathering wood/stone/metal. I haven't actually gotten far into the game. -- Scratch that, 4 times now (this last time while typing this).
@Fjjfjfj I disagree that both 'time to payout' and 'cash per second' should be shown. The developers were smart to have the higher level managers (that show cash/sec) cost Angel Investors. Once you have enough AI that you can actually afford those, the companies they affect should already be moving so rapidly that seeing the time to payout becomes pointless (especially since nearly all are stuck at "Almost There"). Their solution is probably the best one they could have come up with without expanding the UI.
Starting from "million" on, the prefix (the first part of the word, in this case "mil") stands for a number. Mil means thousand. Million is a thousand on top of a thousand, which ends up being 1 with six zeroes (or 1,000,000). Bi (for billion), tri (for trillion) and so forth, represent the numbers 2, 3, etc. So each next step after a million is counted upwards using the latin prefixes for counting numbers. In order, they are: bi (2, billion), tri (3, trillion), quad (4, quadrillion), quin (5, quintillion), sex (6), sept (7), oct (8), non (9), deci (10, decillion), undeci (11), duodeci (12), tredeci (13), quattuordeci (14), quindeci or quinquadeci (15), etc. Keeping these facts in mind can help you determine how far away a upgrade's cost is from what you currently have and are making.
I think the thing I love most about this game is it's forcing people to use math and teaching people how the number naming system works past 1 trillion! As a former math tutor, this puts a big grin on my face.
Addendum to my previous comment: Before 700 or after 900 newspaper, the oil company is far and away your best producer. For those who don't know why, that's because the newspaper provides bonuses to the income of other companies at certain levels (check the achievements). Once you reach the 700 or 800 mark for newspaper, be sure to have at least 900 movie studios and banks, respectively.
If you have 800 newspaper, the bank makes more than the oil company. Also, at 700 newspaper, the movie studio nearly produces as much as the oil company.
Suggestion: Have special (hard) achievements that provide bonuses across resets. For example, make themed investments that require certain companies be above a certain level, while owning 1 or 0 of all other companies. "Connoisseur" -- only own significant investments in food-related businesses (lemonade stand, pizza delivery, donut shop, and shrimp boat); "Entrepreneur" -- only own significant investments in high stakes investments (bank and oil company); "Entertainer" -- only own significant investments in companies that provide entertainment (news paper delivery, hockey team and movie studio); "Tycoon" only own significant investments in oil companies; "Motown" only own significant investments in the car wash (hoping people will get the reference here!).
I have not experienced a full reset, so this advice might not work for everyone: but I find when my income doesn't update properly (after being offline for hours), refreshing the page forces the game to update its values. In other words, I load the game, see the numbers aren't right, refresh the web page, and the numbers go to what they should be. Hope that works for others. Also, periodically exporting your current data to a wordpad document might not be a bad idea. I do it once per day.
