Why are only the PS4 and PS5 versions being censored and the Xbox and Windows version not?

It's in compliance with Sony. Nintendo does the same thing.

I just realized - now that I live in LA, I can go to Power Morphicon. However, I'm not into Power Rangers, only Sentai (and Rider, Ultraman, Godzilla, etc.) Is it still worth going?

Having not been myself(though god I wish I could), it's kinda up to you? PR is for sure the main attraction, but they usually have a booth or two dedicated to Sentai actors.

I'm just not sure what it's like, so I was hoping people who have been to it could offer insight.

As of right now, it looks like the guests and panels are all PR-specific, aside from one stunt actor from Sentai. But maybe there's Sentai/Rider merch and cosplays that could make it more worth it?

Well I recently started up the main Toku lines today. (Rider , Ultra and Gavan)

I have yet to watch Tomica which lasted 3 series.

Apart from the shows on DVD I watch now I can catch Toei's major shows.

As this is now the case are there any I need to watch out for on the new Toku channel? Not USA locked BTW?
