Especially when people start talking about companies like ZeniMax and Square, which are each worth billions of dollars.  It really doesn't make a lot of sense.  It would take a very long time, if ever, to see a return on that kind of investment, especially when you're cutting out part of the market by doing so.  It's unnecessary.

Microsoft is doing the right thing by starting up studios for a fraction of that.

Ugh, no. The only people who would gain from that would be Microsoft.

They would have no creative freedom, see Rare.

The games wouldnt sell as much.

No more modding community.

Would be a good buy for the Xbox brand, would be bad for pretty much everyone else. If they were to buy someone a better proposition would be a 3rd party who they already have working relationships with like Epic.

I don't think that would happen simply due to the fact that MS has built up their internal studios.

I wish they would so Bethesda would stop commenting on Nintendo acting like they would support a Nintendo system if certain criteria was met.

Sure they could, but I'm good with them having some freedom. They pump out great games, why mess with something that is working?

Now, they should pick up that high up person that left Ubisoft's Assassin's Creed. Give them some money to come up with a cool project. That would be exciting.

Do you think they will buy ReSpawn? That one seem more likely to me. But I don't think they will happen either.

What a mature thing to say. 

Modding will come to Xbox One at some point, they've said so.

They said that it's up to developers to support it, not that it will definitely come at some point, two very different things.

I'd rather MS to make their own Fallout/elder scrolls-like game.

Anyway, I agree that only MS really stand to profit out of this.

If MS were to buy a big company though this one would make the most sense, they're on very good terms with Bethesda.
