You mean the vote that was boycotted by 6 of the 15 soviet occupied countries due to how it was phrased among other things? There was no independence option in the referendum, just how should the USSR be preserved.
Also most of the Easter European countries voted to declare independence shortly after.
I was around 20 at the time and in one of the boycotting countries. We later had a vote for independence, I think the support was around 80% or 90%.
True, if you wanna play games with really high requirements you need to cough up mu h more than 700 euros, I'm just saying the Steam Deck is better value than a PlayStation.
