CRPG = Compromised Role Playing Game. It's always been based on a superficial resemblance to tabletop (i.e. "true") RPGs, on structure. That's why Wizardry is a CRPG, even if it has less room to embody a character than games in other genres, because it 'looked' like a RPG from a distance, meaning the audience sees a party, stats, equipment, combat turns, randomness. It didn't look like an action game, adventure, sports, driving, etc, and none of the games in those genres looked like RPGs. CK2, Football Manager, etc. do not resemble the structure of RPGs. Since a CRPG currently can't be a "true" RPG, no matter how close they come to emulating the degree of possibility of one, superficial resemblances are an adequate signifier. Better than things like "I can talk to NPCs." Well you can do that in an adventure game. "I can play a role." Not really, not without a more complex simulation than video games are able to provide. "I can make story choices." You can do that in CYOA, adventure games. Making choices is only one part of RPG structure. You need all or most of the parts.
...At least if they want to emulate traditional RPGs. I've never played or seen any tabletop game that didn't follow the basics established by early games like DnD. I tend to believe that the original definition of a term is the most true definition for all time, and anything after that is second place, or people trying to adapt terms to serve their own agenda. Defenders of decline People tell me there are tabletop RPG systems without stats, attributes, die rolls, rules, character skill limits, etc. but I would consider these aberrations and thus not fit standards by which to judge CRPG-hood A better argument would be "stats/skill checks are unnecessary because the computer can handle all that information," which might be true if we were at a point where game engines could provide the feedback that lets us know just how strong, intelligent, charismatic, wise, dexterous, etc. are character is in relation to all other beings in the game world. But they aren't, so numerical data is still useful for measuring where we lie on the world scale. Of course, popamolers have a problem with the idea of numbers even being present on a screen, even if they never would be forced to deal with those numbers at all. Is it any wonder Kwanstain performs poorly in math?
