Because Cold Steel 2 sold 4 thousand copies or something ridiculous
Where are you getting this from? I hope not from steamdb or whatever it goes by now - those sites have always been wrong.

The very famous CSV here which records first achievement clears has Trails 2 at 17k steam users, of whom a number undoubtedly got it on sale for fairly cheap.
Basically if you estimate the multiple of Playstation users to PC players, probably could do that from a survey on the Falcom subreddit for example, you can probably estimate total sales revenues for Cold Steel 2 overall for example, across all the platforms.
Edit: tbh I think that's actually a lot of money, if they could get their shit together and then do a proper contract for CS3 it should break even considering even an average sell prioce of 25*17k is a lot of money. Localisation is like 9 months of work for 2 Durante programmers and 2 translation people and probably the equivalent of 2 full time employees of other expenses I believe.
