Wasn't Sony better off making Western games for the Playstation brand? Especially their love child was The Last of Us series which is getting an HBO series. I would rather prefer KT trying to buy Square Enix over any of these 2 American Branches
Big no to Sony or KT. Can't stand Jim Ryan or KT's CEO. No to Google either (not really a Stadia fan). Square Enix is a huge publisher, whom owns the western publisher Eidos. I don't think I'd want any entity to "purchase" Square Enix, because not many favourable ones could afford them.
Honestly, only Microsoft and maybe Rockstar would be interesting, though Rockstar is worth just under double Square Enix's worth so naturally it's not too realistic. With how Xbox properties are viewed in Japan, Microsoft making a play at Square Enix would be incredibly bold, though I think they'd treat them alright under Phil Spencer.
