I did math and one girl from pachinko at 900 kobans is 34 Euro. Current event offer me girls(47 total) for total of almost 1600 Euro. Now here is the thing, in case developer are reading this. Why price is so fucked up? I will never buy any kobans (and I never did since release because fuck your prices). It's flash game (and honestly quite low effort at that, sorry, but everyone knows this). If you cut price to 10% of initial value... maybe then I could justify paying for some girls, still 160 Euro for 47 girls is very high amount and I would really hesitate to pay 1/20 of my monthly salary to do so.

Long story short - current prices are laughably retarded.
