Ok - apologies, I must have misread it.
It's just to me - discussing Soviet attempts at gamification without mentioning things like the law I described or placement of peasants back into serfdom (after they had been granted freedom 60 years earlier) is akin to discussing whether Nazi train schedules were effective.
I think there is overall (including today) some pretty strong internal difficulty when claiming to "gamify" work but still retaining the context of a hierarchically controlled workplace where work is mandatory, with penalties tied to the "game". Then it devolves into just another method of workplace accounting & control.
