CRPGs based on TT rulesets and classic JRPGs aren't the same kinds of turn-based games. CRPGs have more in common with SRPGs and games like X-COM, the latter of which has been increasing in popularity when you look at all the games with turn-based tactical combat now compared to a decade ago.

There's no way all turn-based games are dying out. Some types are more popular than ever, including Western CRPGs. If anything, it's Realtime with Pause that's getting less popular in that space.

It's a design choice born from I'm playing the game while eating, if I twitch for timing I'll spill my drink

No it isn't. We had action games on the NES. pitfall wasn't turn based. It's a design choice that allows greater tactical choices.

They were never about hardware limitations. Limitations of imagination of the designers, maybe, but we've had action games for 35 years now.

Actions such as ‘press the trigger and your character will shoot a gun’ and ‘press the button and your character will swing their sword’ can now be easily expressed without going through a command system.

And yet we can't purge ourselves of the awfulness that is quick-time events. I don't buy the argument. It's an attempt to handwave away trends without discussing real causes and effect. If the suggestion here were true, other similar mechanics, such as QTEs, would have been dead a long time ago, not be a core element of a huge number of triple-A titles.

Being confident in your answer doesn't make you right.

More than one type of game exists. It is always a creative choice. Always has been. I could go into examples, but plenty of people have already provided those.

Fire emblem is super popular.
