Take 2
EA
Ubisoft
Capcom
Any of those would be a huge get just for the ips alone. Sony is a big company, whìch has headquarters around the world. They could probably take over something like Ubisoft, if they really see that company would be beneficial for them. I only care Assassin's Creed / Watch Dogs when it comes to Ubisoft, I feel like if Sony could take their story telling approach (ala Insomniac, Naughty Dog) to those ips, it could do wonders.
But I also think this topic has been brought up so many times, that Sony probably wouldn't acquire anything massive (as Microsoft did with Bethesda/Activision Blizzard King) from now until 2025. I'd like to be wrong and surprise us with headline news "Sony enters negotiations to buy ______". I'll believe when I see it.
I'm interested to see how all these Microsoft acquisitions, game streaming services and the rest of this current console generation games will play out 5 years from now (2028).
