If it runs on a computer, it's a cRPG, period.
If you're talking about the original tabletop game, then you talking about RPGs.
Basically every JRPG can be played on a computer.
The Witcher 3 is an action RPG that can be played on computers.
Neither of them are "CRPGs".
They're all cRPGs.
JRPGs belong to one subgenre of cRPGs, while action-RPGs (ARPGs) belong to another.
The problem with hijacking the term "cRPG" for some other purpose is that then we're left with no other clear term for "computer role-playing games" to differentiate them from tabletop. Therefore, it's best to leave it just alone. It's a category with a very clear meaning; it's really hard to misunderstand it, so why mess with it?
You can then use the term "oldschool cRPGs" or something for what you're currently referring to as "cRPGs".
You guys sound like shitlibs trying to redefine "a well-regulated militia"
They're all historical abbreviations for words that meant something different at the time.
1. RPG meant D&D: dice, characters, stats, role playing (making up stories), and usually no tactics.
2. Early computer and console variants copied the mechanics but left out the "role playing".
3. Later computer (PC) variants added grid-based tactical combat.
4. Rogue and roguelikes pared down to a single main character and randomized everything.
5. Diablo and first-person 3D computer/console games added realtime combat.
6. A bunch of fucking spergs hashed and rehashed these dumb genre labels and eventually settled on TTRPG for #1, CRPG for #3, JRPG for #2 because console also starts with C but Japanese console games kept the genre going long after PCs progressed to #3, Roguelike for #4, ARPG for #5, and more (but no one cares).
Only the first has actual role-playing but they're all called RPGs. The rest are all played on computers and/or consoles but that doesn't make them all CRPGs, it makes them.... Video Games.
