Here's a spreadsheet: [url=https://docs.google.com/spreadsheets/d/1vVsFMwrjpypXuO9RqHvmWQLXHjdOOe7JxHOXj_3I3oY/edit?usp=sharing]google sheets[/url]

I made this spreadsheet (someone else made a simulator, but I can't find it, and calculation produces better averages), and found out some "fun" facts about star force.

edit: this doesn't account for the little game, because I have no idea what that actually does. That probably accounts for discrepancies. If someone can find fault with the actual math, please let me know.

edit2: I rebuilt the math in my sheet; now the cost to get the next star is:

the expected number of tries to succeed * (the cost of attempting + the drop chance * the cost of getting from current - 1 to here + the boom chance * the total cost to here)

which is, I believe, correct.

The corrected formula produces MUCH lower numbers, so many of my "fun facts" are fiction, though 5 is completely correct, as we all knew. Here's the updated number of mesos to 15 star tyrant, not including new pieces to replace old: 25,617,913,857,047,700, which is definitely more than anyone has, but is not more than have existed (?).

edit3: I gave up on actually working out the formulas involved, so I just ran a simulator and posted that data instead. Enjoy.

I made this spreadsheet (someone else made a simulator, but I can't find it, and calculation produces better averages), and found out some "fun" facts about star force.

- 5 star tyrant is actually more expensive than 15 star CRA
- 6 star Nova is only slightly cheaper than 15 star CRA
- at 200m:1k NX:mesos, Nexon would have trouble buying enough NX to 11 star tyrant gear.
- at that same ratio, there isn't enough money in the world to 12 star tyrant (nvm the mesos).
- 13+ stars on tyrant is as stupid to try for as it looks.
- 15 star tyrant requires more mesos than there are particles in the (known) universe.
