Whoa, whoa... who hates on MT Framework?
It ran stable, it was powerful enough to do all modern effects at the time, it could throw a ton of characters on screen at the same time, it ran on everything from high-end consoles to 3DS and Mobile (albeit through a variant designed for "lite" platforms), you could do 2D with it, it could be used to do cross-platform like EX Troopers across platforms as different as PS3 and 3DS, it still holds two generations later to make something high-end like Monster Hunter World...
Seriously, I've never heard a bad word about MT Framework, maybe you've got stories to tell because I'm genuinely surprised to hear somebody call it "horrible". I'm curious, what's your side of the conversation?
Certainly RE Engine improves things (although us gamers think of it as "better graphics", whereas when the developers talk about it,
the switch is as much about efficiency and development collaboration as it is any next-gen graphical feature impossible in the past,) but RT Engine begat RE Engine. One was successful for over a decade across multiple platforms, and the general teams who made MT were called upon to make RE when it was finally time for a full rewrite. Capcom builds dependable, performative, impressive game engines, and RE is a continuation of that legacy, not IMO a course correction.

(*BTW, it
might have been catastrophic if Panta Rhei actually was the successor for Capcom, instead of RE... Although Panta was doing some amazing things with fluid simulation, global illumination, PBR, and other advancements, there is limited talk of this engine also changing the development collaboration pipeline to bring it in line with Unreal or Unity or even Crytek, and that's a big part of the production speed of RE. Ultimately, the one resulting game project running on Panta was visually flabbergasting but functionally very limited, confined to procedurally arranged corridors and caverns, no known hubworld or larger world context. It's unknown how Panta Rhei could have been applied to an open-world project like Dragon's Dogma 2; maybe it would have worked? Maybe not? Luckily, RE Engine has proved itself in its stead and now it's easy to trust that the engine will deliver.)
