One of the quainter, more obscure attractions in Moscow is the Museum of Soviet Arcade Machines.
The post-Stalinist USSR aimed to provide a good material living standard to its people, and technologies were bought from the West towards that end (e.g. the classic Lada was a copy of an Italian Fiat car).
Ergo for arcade machines, which were developed on the basis of American exemplars brought over during the 1970s (although their graphics and tech was around a decade behind that of the US, as in much of the rest of the economy).
Amusing, telling fact: The electronic screens were produced exclusively by the military factories that also made radar screens for the Soviet Armed Forces. Why? Because none of the civilian factories had the requisite capital equipment to produce them. They were rare and in high demand, with the standard rate for a round going at 15 kopeks (average salary: ~200 rubles/month). Consequently, although they were very expensive to produce – one arcade machine cost as much to produce as two Moskvich cars (which cost about 7,500 rubles around 1980) – they were nonetheless a highly profitable item for those military factories’ ledgers.
There are several dozen arcade machines in the museum, which also hosts a cafe. You can buy 15 rounds for 450 rubles in the Moscow branch of the museum.
They were all surprisingly hard to beat. For instance, my best performance was in this snake game, and I couldn’t get past the third level.
