I wouldn't say they "deepen the RPG aspect".
They certainly add a great deal to the overall experience, but they don't make the game any more or less of an RPG.
If RPG means a role playing game, playing a role by taking the course of action you deem that role would take, then any element that enhances the players capacity to play that "role" certainly deepens the RPG aspect.
Yes I have. Look back and see the example I gave.
You did describe this hypothetical game in great detail but you did not demonstrate how it could considered be an RPG.
Interaction is not required. You could have an RPG set inside a small, featureless room where you don't encounter anyone or anything. It wouldn't be much of an RPG, but it would still be one.
an RPG without choices would be incredibly boring - in fact, it would outright svck... but it would still technically be an RPG.
Please correct me if I'm wrong, but it seems that you are proposing the following:
A. RPGs must have stats
B. This hypothetical game has stats
C. Therefore, it is an RPG
Unless I'm reading the wrong post, I fail to see this proves that such a game, with stats but no choices, should be considered an RPG. Which stats does it have? STR, DEX, etc? Why those specifically?
We can certainly agree to disagree about what an "RPG" means. In my view you must be able to play a role within the game. In order to play that role you must be able to carry out actions appropriate to the role you are playing. You must be able to choose, my character is "X," so he will do "Y." You could have a million stats in that hypothetical game, but if you are not making choices, you are not "playing" or "enacting" that detailed role.
Once again, video-game RPGs work differently to pen & paper RPGs. Please stop using this invalid comparison.
While I take issue with your casual dismissal of the relevance of pen-and-paper role playing games to any discussion of video game role playing games, this comment makes me wonder if you actually read my post.
As I mentioned above, a video game RPG obviously requires the ability to track data related to the PC, since it is not a human GM, and in order for there to be any progression, "stats" must exist in the game mechanics. If I am not mistaken, you are suggesting that certain very specific stats are essential for a videogame RPG, such as STR, INT, etc. I maintain there are many ways for a video game RPG to provide for character progression without these specific stats.
You can do all of those things in an action-adventure.
Are you proposing that if you take an action adventure game and add STR, INT, etc., it suddenly becomes an RPG, even if it did not allow you to play a "role" with meaningful choices?
