Do certain consoles / genres target certain demographics in-game?
Solution 1:
From personal experience, first start by developing for a console that has more users, on the other hand, if it resembles a real-life system that failed, don't even bother. Then it all really depends on the genre(s) that are popular, the genres that you're good at, then the skill of your developers, don't be afraid to hire outside developers, and always let your developers experiment the pay off is well worth it (try for at least a 55% success rate)
Solution 2:
There is no mentioning of details like this in the game manual, and the game manual usually details these things pretty well. Because of this, I have always just assumed no.
Solution 3:
I don't think the developers had such a big idea in mind. I think it's the same, and this is why. After playing for a long long time, you get to the point where the only thing you can do to improve your sales is produce for your own console, and that console is completely default, meaning it's always the same. So it can't have any possible demographics, so I believe it's the same.
However, maybe the game itself can define a demographic, such as "Animal" can be just for children but I don't think that's the case either.
What I feel is that the only difference between the younger and the elder audiences is the difficulty with which it is acquired. I noticed that, by the end of the game, I had 999 in every category except in the last one, which wasn't possible even by spending 1 billion dollars on lunar writing advertisements. The only way I could get to 999 on 60+ was when the audiences got older.
