I do and I don't. For passionate fans of any team, their home arena is almost a second home. I had Caps season tickets for a decade before moving to Florida, and when the NHL games got something amiss with Verizon Center (now Capital One Arena), I could spot it right away, because the place was where I spent an aggregate month and a half worth of my evenings of every year, cheering on my team.
The logistics of getting every single home ground into a video game--getting permission to use it, scanning it in, digital rendering--are not easy. AI can expedite the digital parts, but if permission never comes, say, or if the venue's name can't be used for legal reasons regardless, that's going to leave users with, say, "Arizona Arena," because a casino had bought the naming rights. And fans of a team whose home ground isn't fully "in the game," tend to be disappointed when that happens. I remember a few years ago, fans were getting miffed that Madison Square Garden wasn't officially licensed in NHL, and they were blaming the devs, when the issue was that the New York Rangers didn't get the licensing agreement in before the deadline.
So, multiply all of that, by...how many teams are in FC 25, again? And in how many countries?...and I can empathize with the magnitude of it all. And that's not counting how much data, that that many grounds would take up, on, for example, a stock PS5 internal storage.
Would having every stadium in game, make for a better experience? Absolutely. But between the not-quite-there technology, and the prohibitive logistics of capturing so many arenas, in so many far flung locations, I can see why the game uses generic stadiums for lower tier leagues.
