If you’re going to invest in something then you should seek to own it. Giving a studio money to build them up so they can be “free” is stupid.
They own the IP which is more valuable
Similar to Kojima productions. They invested in Death Stranding and own it from this point on, and own the engine is was built on.
If Microsoft wants kojima they have to get him without the IP and Engine he’s worked on for 4+ years.
And if they buy Kojima productions they will be buying a shell of a company because KP if kojima decides to ever retire and make theme parks or movies, isn’t really much of a company and you can’t own the heads of a company.
IP will always trump talent, talent can leave anytime they want
