When Xbox was the lead platform in the USA, that was the peak of JRPG slander online. their audience do not buy JRPGS. They were the ones that said " you should play a real RPG like mass effect or skyrim"
When Lost Odyssey launched, Microsoft was still very far up its own ass about Halo 3, so instead of making sure to properly market this exclusive they had, this return to form for a legendary creator beloved by millions, they instead kept the dashboard and storefronts filled with Halo 3 ads instead, because they believed it was more important to serve marketing for a 4 month old game than to give literally any spotlight to Lost Odyssey.
By the by, Star Ocean 4, Tales of Vesperia and Eternal Sonata -- all of them temporary exclusives -- were treated much the same, shoved into some corner of their websites / storefronts often branded shit like "Exotic Titles" which isn't racist as fuck at all. Unsurprisingly, all 3 of those titles ran the fuck away from Microsoft as soon as their exclusivity contracts ended and launched improved versions on PS3 where they were much more successful.
Full exclusives, like Blue Dragon and Magna Carta 2, were handled similarly. BD's Mistwalker took such a gigantic hit on both it and Lost Odyssey that they gave up developing HD games permanently to this very day. Magna Carta 2 was pushed so little it led their developer to bankrupcy -- they've not made another game since, and as a result Microsoft cannot get consent to handle the IP, so it's not even supported by modern Xbox Series' retrocompatibility features. It's forever stranded on a console with 50%+ failure rate that will inevitably become unobtainable in working condition.
You'd think they would have learned the lesson, but a few years later they did what they did with Kamiya's game. A few months back, Phil Spencer stepped on stage for Final Fantasy XIV's Fanfest to talk about the Xbox Series port of the MMO and he couldn't even be bothered to pronounce the game's fucking world's name correctly -- it is 6 letters long.
SEGA Sammy and MS are perfect for one another. If Microsoft could legally do it, I bet they'd also have a massive gambling addiction exploitation industry like Sega does.
