Ok, it seems that most people who consider TW3 more of an RPG than CP, is because your actions have more consequences in the world. This generally seems to be important for alot of people here to consider the game an RPG. I completely disagree. If anything, the genre were your actions affect and have the deepest impact in the world are strategy games. Other than that ANY story driven game with zero RPG elements can be based around a choice and consequence system.
Also consider the fact that many old table top RPGs (and pen and paper, and video games) were simple dungeon crawlers where your "choices" had no impact at all. The objective was to loot and survive the dungeon.
RPG is more about your character (or your team). How you progress and develop your character to deal with the problems you face against the scripted content. The game should give you different options on how to do that, depending on YOUR choices in how YOU have built your CHARACTER (or characters if it is team based) . Your actions may have zero impact on the world state or the progression of the story. But you get to complete the story on your terms, (with the game providing you different ways to do it, a.k.a RPG, but your choice shouldn't necessarily affect the world state or the story, as wasn't the case on several if not most old pen and paper/tabletop RPGs.). On said dungeon crawler a rogue could avoid traps, other characters will have to deal with them, and combat itself will be handled in various ways depended on your character, or avoided altogether. Just a few examples.
These elements exist in CP. I played a melee tank/dps character. I couldn't hack. I did not hack anything. I did not use stealth at all. I did not even shoot. I butchered everything on my way to complete the game. I used several shortcuts since i had the strength required to open doors. I avoided several fights because i was intimidating enough for people to fear me etc. On the Witcher every single encounter, you had to handle it like a swordman. Sure you could have some variation if you were more focused on signs, but Geralt is a swordman through and through.
I consider TW3 to be more of an RPG despite the fact that the actions have no real consequences. It is not that Geralt can change the outcome, it is that the game makes the player feel like the decisions mattered. The roleplaying is an illusion, as it is in almost all CRPGs. The player must stay within the bounds of the assigned role. TW3 holds that illusion better.
V's reason for being is to collect money, gear, and implants. As I see it, how the player answers Dexter's question is pivotal, whether or not they tell Dex the answer. One answer follows the main quest to a predetermined ending with very little illusion that the role is anything but destiny. The other answer avoids it, and really has no ending. The player gets to do as they please, but without any real support from the game in the form of an ending. The latter probably results in 100-200 hours of playing crime fighter on the streets of Night City. Eventually, all the fixers will stop calling. No matter what the player does in this game, V is one type of failure or another.
Again, for CP2077, it goes back to how Dex's question was answered. That is the real role playing decision that makes a difference. I don't see combat style having much to do with anything. Fun, yes, but not a significant decision, and not one that is recognized by the game.
As for dungeon crawl table top, that tends to be roll playing. The best table top RPG games that I played were not dice-bound, and even the GM had no idea how it was going to turn out. The game system did not matter. It could be anything from Runequest to Ars Magicka to AD&D. What the characters did mattered and could change the outcome. This is very hard to replicate in a computer game, so we end up with very limited choices.
The bottom line is that there aren't really any good computer roleplaying games. They are all different levels of not being an RPG game. As a former table top role player, I know that both games aren't really RPG games. They are simulated RPG games, which is the best we can do until Diamond Age tech comes along. I still think that TW3 is a notch above CP2077, but CP2077 has unrealized potential that could have changed that.
