Incorrect. Sony owns the Spider-Man IP movie rights, this is not the case for video games. Marvel's Avengers would not have been able to put him in the game if that were the case.
edit: Maybe wrong on the Marvel's Avengers game front as I forgot he was a playstation exclusive character for the game, but Sony still does not own ALL spider-man rights, but specifically movie rights.
In this case, I am almost positive Larian just isn't providing those sales figures. Before I didn't spend more than a minute googling how many copies sold, so 22M may definitely be too high, but I would honestly still be surprised if Starfield outsold BG3 at all, even if 11.5M of Starfield's 12M players were purchases, and not game pass, which is a super generous estimate.
But I have more than a minute now, so let's look at steamdb. There are 4 analytics things that provide owner estimations there. The spread on these estimations is insane, ranging from 5.5M to 27.7M. But the two middle ones estimate sales at 13.3 and 14.9M. Both are higher than the 12M players Starfield has reached through both sales and gamepass. But. These are steam specific numbers for BG3. It also launched on GOG, though I'm sure those numbers are nowhere near steams numbers. More importantly, it also launched on ps5, and who knows how many copies sold there.
Or maybe the achievement extrapolation method is the most accurate and it's between 7 and 8 million copies sold. There is still a very good chance even those lower numbers are beating Starfield in overall sales.
Regardless, this is all some nebulous as fuck guesswork, but I feel like it's more likely than not that BG3 straight up outsold Starfield. And even if it did not, Starfield had years of hype behind it, and Bethesda has been one of the biggest names in gaming for many years now. Larian was a niche studio making niche games (yes, the D:OS series was quite succesful, I would stay say they were niche though) so the fact that they're even in competition with the Bethesda juggernauts these days is quite impressive for them.
Dunno if this is the case for wherever you got your sales figures from, but a lot of the places that track best-selling games only track physical releases. Or they might also track digital releases if the publisher provides them to whoever is doing that tracking, but they often don't. BG3 does not have a physical release (yet).
And a quick google seems to back that up. According to Phil Spencer the other day, Starfield has had "over 12 million players". I'm assuming this is a combined figure of sales and people who downloaded it through game pass. So, less than 12 million copies sold, and probably a good deal under that cuz I assume game pass would be a pretty decent chunk of those players reached. If the top result when googling is accurate, BG3 has sold 22+ million copies. Prolly enough to crack that top 20, I'd guess.
Not a movie, rather a show, and also not complete yet, but The Dragon Prince on Netflix is pretty good. The titular prince is a dragon, but there are human princes as well, with one becoming a king actually pretty early on. And King Ezran absolutely tries to bring people together peacefully and with honorable intentions, though there is some action/fighting as well. Caveat, while it is a kids show, it might be thematically better for kids a bit older than 6, as some of the themes can be a bit dark for a kids show, but I'd just recommend you watch a couple eps yourself before showing it to the kiddo and decide for yourself if it's appropriate.
Also, someone else mentioned Avatar: The Last Airbender in this thread, which is also excellent, and if you happen to be familiar with that show, it has a lot of similiarities and it's some of the same writers and directors of that show.
Not that I want to defend EGS here, but I would like to point out that they actually have had a shopping cart for a bit now. Hilarious how long it took them to implement, but they do in fact have one now.
If you want something that resembles an app, you can even make a shortcut in firefox and put it on your home screen so you can have a dedicated kbin button rather than setting aside a firefox tab. Works great.
