Well, the issue with it being or not being inconsistent is a matter of perspective, but the main gripe here really isn't the consistency or inconsistency of the character, rather the lack of a choice in the matter when it was previously there and frankly seemed to me and others as a character trait that you could have. It's more of a narrative inconsistency, which if we are talking about art is something that deserves some criticism. Now I don't care enough to make a thread about it and I'd certainly never have mentioned it if there wasn't a thread about it, frankly I have no real world issue with drinking, smoking or drug use, but it still made me think at one point that this character started smoking without my choice when previously every time I was given one. It just seems a bit weird to continuously give a choice then arbitrarily remove it and the times V smokes without player input isn't really justified narratively, It is just thrown in there haphazardly, it's especially noteable given that every other time V is given the opportunity to smoke or drink it actually has a narrative context behind it. It just seems to me that either the writers got bored of this choice OR (and I think this isore likely) a separate writer or designer forgot or did not know that these narrative events were happening and the scene was just made and never accounted for or when it was caught it was too far along in the process that the developers thought 'fuck it, nobody will really care anyway'.
As for the discussion about what art is etc etc, I would be happy to discuss it, but it's probably too far off topic to justify a full on discussion here. I will say that I wasn't saying that a piece of art should necessarily be changed, but that demands should be made of it, including demands to change it, as these demands will ultimately affect the art that will be created out of that. Generally however I am in agreement that a finished piece of art probably should be left as is, for better or worse, though a discussion like this becomes difficult in the digital age, especially when dealing with a video game, especially one that has literally been continuously changed over the past three years, even narratively with Phantom Liberty and there's a pretty large narrative issue I have with that, that frankly I wish would be different. Now I'm not the sort of person to make a demand that it be changed because ultimately it is a video game and as I said I fundamentally agree that once a piece of art is done it should stay done, but I would at least make a demand that the writers pay attention to my grievance because I think it is important enough to warrant discussion.
Now I am using the word demand in a very pedantic way and I'm kind of being obtuse for the sake of it, so sorry about that. I don't mean demand in the sense of actively campaigning for an existing art to be changed because quite frankly I don't take that too seriously. I know this thread is literally that, but as much as I don't take it seriously it at least created a discussion that is in some way worthy of discussion and serious questioning.
