Look at them including perfect dark in the list as if they'd have the balls to make another sequel after they botched the last one after essentially using it as a launch exclusive title for the 360... such a shame. Perfect dark 64 was a masterpiece.
Ultimately the problem with Perfect Dark as a franchise is that everyone who made it great went off and formed Free Radical and made the TimeSplitters games.
Blizzard has already been doing that for a while. Also failing with new franchises, not investing in their core games, half assing releases. I hope they actually turn things around for games like Starcraft, Diablo, HotS etc
Blizzard would never have done that if Activision hadn't been allowed to buy them. The new conglomerate will be worse than we anticipate in the same way Activion-Blizzard was.
Most of those are already shit (Fallout, Diablo, Overwatch, call of duty) or shelved 25+ years ago (Commander Keen, Hexen, Phantasmagoria...). Microsoft's own games are rather good compared to Activision Blizzar or even Bethesda.
It's probably because so many of them are mediocre or don't really exist as modern games. It's kinda sad that out of that list, there are so few 10/10 series there.
Microsoft at least owns the trademark on it. Not being a lawyer, I don't know if that's at all decoupled from "the IP" or not, but I suspect they'd be tied fairly close together.
It would also be weird if Mistwalker signed a contract giving MS ownership of Blue Dragon (which is on the list, but has multiple games from different publishers) but not Lost Odyssey. I guess maybe the solution would be to remove Blue Dragon from the list rather than adding Lost Odyssey. 🤷♂️
