Well, I loved to build and play with these tiny tank and airplane models made from plastic as a kid, but apart from that ... "Star Wars" is the only war-like setting I more or less like. Apart from that, wars were never interesting to me.
Interesting to me were riddles and stories, things to be found out ... Like the stories behind RL words, where they come from etc. ... and that's why I once began reading texts from ancient authors, and ended up loving Archaeology ... I don't think that a younger customer base most games are oriented to liks this "old stuff".
When I read and hear about "more mature games" or "games for a more mature audience", this usually means morebrutality and more graphical violence. I don't remember having EVER seen a game being advertised at an "more mature audience" NOT having that, or, in other words, haviong OTHER themes like that.
I mean, I'm sure one could do a really deep story and drama with lots of riddles and so on for a "more mature" audience, but nobody does this. Why ? Because the younger customer base would not want it. I feel kind of alienated by "the big companioes" focussing at their target customer base which wants some kind of "violent mindless fun", so to say.
It's like I wanted to go to a french cuisine restaurant, but all I find is Burger King or McDonalds. Nobody sells to me french cuisine, because they all see that fast food sells far too well. ... so well that they just don't want to sell anyother thing, because it would not be cost / profits effective to try to make & sell something deep, complex, complicated that only a tiny target base would want.
From a more cynical point of view, making the lowest quality (with the least amount of costs) if it seöös well is far more cost / profit effectiove than selling something ... deep, complex, complicated ... Welcome to capitalism.
