I kind of agree and kind of don't. I mean, if we're talking about brand-new IP that is created after the purchase then sure, that's first party. But when you're talking about long-running, established multiplatform franchises then it still seems like buying exclusivity, even if the way you did it was by buying the developer. Like Fallout, Doom, TES, Dishonored, those are all franchises that have historically been multiplatform, so it feels like you're taking something away.
Now, maybe they'll do like the did with Minecraft and keep putting stuff out on other platforms, and the only real difference will be that on Xbox you get it as part of Gamepass. If that's the way they go then great, more power to them, I have no issue with them giving a benefit to their own customers. It's just when it feels like they're taking something away from others that I get annoyed.
