I think calling Larian "indie" is taking the piss. Larian is independent, in the sense it didn't require external funding from a major publisher. But "indie" is more than just an abbreviation of "independent": it has strong connotations of low-modest budgets / manpower involved which are incompatible with the likes of BG3.
There are plenty. Every year, more roll out. It depends how narrowly you want to define the style of game, but for the basic concept of party-based (non-FPS) RPG, there's not a shortage. Not least because this inevitably includes the host of JRPGs (which I generally hate, but aren't going to pretend don't count) out there. You're also looking at borderline games like the Jagged Alliance series (which might more usually be described as a squad-based strategy game and is relatively lighter on RPG elements) but even still are close enough.
I appreciate that some people find the experience of staring at primitive graphics painful to their soul, but for those willing to do so it's just not that hard to find stuff to play for most of the average year.
Larian WAS "indie" at one point at least, though everyone seems to have different definitions for it. They used Kickstarter for both Divinitys IIRC. I would agree that BG3's budget is too high to be considered indie regardless if they still are technically independent.
And I'm specifically referring to RPGs that prioritize role-playing (as that was the thing Luke mentioned from the video that BG3 is a ROLE-PLAYING game, emphasis on role-playing), very few of those get made. I don't think there's a single JRPG that I'd consider an RPG in my book. I think Catherine might be the "JRPG" with the most role-playing that I ever played, though that's not considered a JRPG. Final Fantasy, for example, features like no role-playing.
It has sold well for a cRPG
It's also niche as it automatically excludes a bunch of people who dislike how it present itself.
Like, I like Pillars and Disco and Divinity. I am the target group. But that's not most gamers.
I think this game is going to convert some people to cRPGs and it's going to be popular with those already in the group.
But many people will completely ignore it because it is a cRPG. Similarly, dating sim games are completely ignored by those outside of the target audience
Pillars is sorta same-y to Divinity/BG if just getting a bulleted-point description and that's it. But Pillars writing is really dense and there's just so much text. Also, it has the real-time and pause type combat that I'm just not a fan of at all, and I think many others are turned off by, it feels more RTS-y than RPG-y to me. I know Pillars 2 added the option for full turned-based combat but that to me means the game is gonna take way longer to get through if you go that route because each battle will take longer turned-based and I doubt they took out combats and tuned the game so playing either way equals the same length approximately. You can't just make a game for real-time and simply also change it to turned-based without fucking shit up. All that is why Pillars 2 didn't sell well vs Divinity or BG3.
Disco Elysium is more niche because it's all dialogue and narrative, no combat. Even with that, it sold over 2.5 million, which is more than Mass Effect and half of Mass Effect 2, which are AAA games, from a few gens back but still that's pretty impressive for something like Disco Elysium.
Divinity 2 sold over 7.5 million without being part of some massive brand or IP. I think BG3 will sell at least 10 million (it sold 2.5 from early access already) since it has the DnD brand behind it and DnD is bigger than it's ever been. To put things in perspective, RE4 Remake has sold 5 million so far, is BG3 still considered niche if it outsells RE4 Remake?
