Well, there was never any info IIRC - everything about this game I know is basically reverse-engineered by people who made Wiki page. Heck I myself spent like a month of checking things when I just started playing the game and even made a big comment thats linked in one of the wiki pages.

Ah all thats left is to wait till they fix this damn lag, and then we can start checking/analyzing. For now I am only pissed at the huge price drop of upgrading you main 3 stats. Less than 1k6 per upgrade down from over 152k it was before close to the end. Thats probably close to like 50-100 millions of cash basically lost for older players.
