No offence, but I do think you dont understand how probability theory work.
Your basicly asking me to prove that god dont exist.
No I'm not. I'm just saying don't use an exact number when you have no idea what the exact number is. It's fine to feel that it's not use that often, but it's not ok to say that only 5% of the user base is using it. You're taking a big leap there.
I'm going to ignore most of the god talk and mumbo jumbo you posted, as it just seems like a way to try to escape the situation you presented yourself with.
Theory A:
The majority of customers use Forza Vista a lot and find it very usefull.
Evidence supporting this theory.
Few users on GTP forum.
I have not ever seen anyone discusing it anywhere else than this thread. This dosen't mean that such thread's dont exist but the proberbility goes towards that there are very few of such threads compared to how many threads where people are discusing other area's of the game.
There is very few people who talks about Forza vista = its not something many people care about. Dont you think if Forza Vista was the do or die aspect of the game then more people would discuss it ?
Which is all irrelevant to me, and even yourself, because you yourself said that users posting opinions on forums is no way accurate statistical evidence, so I have no idea why you're continuing down a path you don't believe in, in the first place.
Either way, it was never stated that the majority of users use Forzavista alot, more so that enough users use it to warrant the attention it gets. Photomode is a fraction of the userbase in comparison to the grand scale of the game, but does that mean because it's not discussed as much as actually playing the game, that means it's an irrelevant feature? I think not.
Theory B:
The majority of customers dont care for forza vista, and would rather have other game features expanded or improved.
Evidence supporting this theory.
A lot of users on the official forums, who are constantly asking for features from Forza 4 to be reimplemented or improving other area's of the game.
If you browse the official forums I would say that a large portion of the threads in there are threads where people in one way or other way is asking for or discusing other area's of the game they would like to see improved rather than Forza Vista.
Which was never the point at hand, because it was that the budget is what is restricting those features that people are asking for that used to be in the game in the first place. They choose to remove them, not because of budget. I don't understand how you correlate the two, that these features we used to have in the past where removed because the money was sent to Forzavista instead. It doesn't take money to leave an existing feature in a game, it may take some money to get it more optimized, but nothing that is going to be a considerable amount I would imagine.
Again, just because every single wish isn't answered doesn't mean anything for the topic at hand. Each game is obviously expanding and improving features, and even adding new ones. Maybe at not that great a pace, but that has been something that has been happening way before even Forzavista came around.
I'm not going to browse the forums and look for them, when you yourself stated that it is not evidence in any way.
And no a few users on a message board who has and opinion about it is not a usefull statisticall evidence.
There is always going to be more on the official forums posting their distaste for an aspect of a game, rather than praise for a different aspect.
Always. Those that are pleased are likely to not even bother going in to complain. That proves neither this nor that, though, because again, it is not evidence whatsoever.
