Using of a blockchain for gaming would be a stupid way to use it, just like dick pics and fart sounds in the Bitcoin blockchain. Nothing of those truly need censorship-resistance.
In most cases that's true. However, Doom's predecessor, Wolfenstein 3D, was banned in Germany for a fairly significant length of time (for obvious reasons). So there may be some fringe cases where censorship resistance could be a legitimate need.
But a blockchain remains an incredibly inefficient way to do it. Particularly when filesharing technology has come such a long way and is purpose-built for that task.
I'm talking about specifically the Bitcoin blockchain because it would be so inefficient. BitTorrent is a better network for that, the user can just download the files, then run the software locally.
When speaking of censorship-resistance, I believe it should solve something and make things more efficient, like for instance ransomware. Everyone sees it as something nefarious, but what Bitcoin actually did is it made a market out of insecure software, therefore making software builders release security updates/patches more often. There was a gap there that Bitcoin filled.
