What was the original title? I missed it :(
"So Switch IS really taking over for the Vita now..."
The NESbot_feed account is very useful for finding the original titles of ERA threads. :P
Anyway, I definitely see the pattern and it's definitely partly due to Sony's censorship policies. Compile Heart (who made the game in question) has also announced other games for Switch that have a similar... reputation.
It seems to be a changing of the tide. I have my doubts that these games would've started popping up on Switch if Sony hadn't started this recent policy of theirs. I'm also thinking this will start attracting the otaku audience towards Switch in Japan (and maybe worldwide) faster and faster. Which in turn, would mean more notable Japanese support could be in the Switch's future.
Vita clearly was the darling of publishers in Japan despite 3DS selling eons better than it. I've always felt it was this very reason, that the otaku audience was very much catered to in Japan while 3DS in Japan was much less so. That's just my opinion, but Japanese games did very well on Vita in Japan. Not just these kinds of games, but Japanese games in general.
