Jktu: But mostly I agree with you: if the developers promised a Linux version, they should. It is a pity that they are not Japanese and do not follow the code of bushido, there is strictly: to lie or not to fulfill a promise - it is unacceptable, did not fulfill the orders of the boss - you cut off your little one, the next time - nameless and so on, and if you embarrassed yourself or the organization - you do a seppuku. There is clearly a shortage of software developers in the domestic gaming industry.
They just don’t live on more than one project.
