I am too old to play turned based RPGs that have also tactical moving, I uninstalled BG3 in 1 hour of playing. :P

Okay, I've changed my mind on BG3 not being as packed as DOS2, while it's true it's just a matter of things being spread out. I went all over the map the best I cuuld and found loads of stuff I missed in act one. I found a little guy on a windmill, Spent ages trying to figure out where he was calling for help from, I didn't even think to look in the windmill until I came back and flipped the first lever I found and I send this guy flying off, he was tied to one of the blades. Lol, first time I had to reload a save cause of f I choice, I had to know what his deal was.

To say the game is good is an understatement but Larian need to keep DOS combat for the new Divinity, while I like this, it's not near as great DOS where I'd be happy to wipe after forty five minutes and try again, here it's just not as interesting even if I am only level five. The skill unlovks are not only scarcely implemented but they are also less filled with choice, you can really screw your build up in DOS or break the game but here it's not great no matter what difficulty your on. Larian were already struggling to capture that true CRPG vibe even though their style is better in my opinion but I feel they were going to do pause combat and at the last moment they changed to turn based.

I'm quote liking what they've done here. It feels half CRPG and half Larian game however I think they stepped into actual CRPG territory here if you ignore leveling. It feels old yet modern. Infact I think it feels very old, I romanticise games like this of the past only to find they aren't all that great on return, here I think they mastered the old and (while not as new as DOS) modernised the hell out of it with only minor sacrifices for production value.

I think Tactical RPGs are dead because they are too slow, it surprised me Baldur's Gate 3 had sold over 20 million units. Good for them.

Replaying Raidou Remastered for the moment. . Love this game and any RPG fan should try it. In between moods since finishing Romeo is a Deadman (loved it) So either this sticks or my ADHD has me switching to something else.

They are not dead, they were always niche (if we're talking CRPGs, that usually have tactical combat). Even back in the heyday of CRPGs (pick your era, whether it's Ultima, SSI's Gold Box, or first renaissance spearheaded by Interplay/Bioware) they were mostly niche genre for audience that wanted P&P RPG experiences converted to video game format.

BG3 made a mainstream splash since it was riding the massive mainstream success of D&D 5e, it's (on the paper) sequel to CRPG classics that are BG1&2, it's made by makers of D:OS games (which have their loyal following), and last (but nowhere near least) had massive media hype (backed by Hasbro).

I think what made the difference was the actual acting and face to face interactions with the characters. It made it much more appealing to the mainstream than just tiny characters with text above their heads. I wonder how popular Larian's previous games would have been if they did that earlier.

Not that popular. Not BG3 sales anyway. I call bullshit on CRPGs being niche, Larian proved that they aren't. The previous user here mentioned most but the factors surrounding BG3 which caused it to boil over are many, mainly larian cultivating a strong base of dans and then piggy backing off an iconic name, doesn't matter if people didn't play it, they recognise it and D&D popularity being up cause of Stranger things as well as the media and gamer hype. I think the next Divinity won't hold that number as you can see with the Trophy data on BG3, they'll be lucky to get half that again but still more than prior Divinity:OS games LT. Even if they done BG4, they aren't getting that buzz cause the game is clearly too overwhelming for the masses but that's not to say it's niche, 10 million waiting for a BG3 level game is not an niche, if the AAA studios out one out tomorrow they'd have 10 million LT if the the game was as good and hype worthy as Larian games but they won't, I'm not even sure they can make them with severe issues. 

I think this subject is a bit absurd since i don't know any other developer except Larian Studios to have Tactical RPGs to sell Millions or tens of Millions.

Almost all games of that genre just sell some hundrends thousands of copies like Vandal Hearts on PS1 and Disgaea on PS2.

The genre is niche except Larian Studios for some reason.

The real reason for its success was the voice acting and the motion capture that allows for expressive emotions

Fire Emblem 3 Houses, sold 4 million+, watch out for Fortune Weaves this year

X Com 2 also sold over 4 million 

Disco Elysium 5 million units

Tactical RPGs (as in, gameplay-wise) are not exactly niche per se, they simply lack production value that are marketable for non TTRPGs nerds. A full voice acted with complex character models Disco Elysium would have sold close to 10 million range. Im 99% sure the next Divinity will sell close to the 10 million range
