I don't know why you're getting downvoted for this. I've SEEN real tankies, doing odd things like cheering for BRICS to rise up or Russia to defeat NATO in Ukraine because late stage capitalist oligarchy counts as communism if it's Russian or something, I don't know?
But the VAST majority of the time I see it used is by neoliberals as an excuse to dismiss literally anyone anywhere on the actual political left out of hand.
And then not release a single game built for or exclusive to it until 2035. Hard pass.
