It's amazing the differences, working on a long term project. How long term? Our first released version was in the mid-nineties - and yes, we're doing more than just maintenance, even now. It's a defense project.
I'm on a team (within the larger project, which is 70-100 people) of seven people. Four are over forty, in some cases by a lot, one is about to turn forty, I'm thirty-three, and then we have our one, shiny just out of college person. We're pretty representative of the project as a whole, with the UI team trending younger than the others. The idea that older people don't know what they're doing, even on new languages, is pretty silly to me.
Conversely, some games have too much plot to be made into movies. With the announcement of a (direct to DVD, anime style) Dragon Age movie, the fan community I belong to when crazy. In a negative fashion. Why? We knew they would never make the choices we made. Heck, it's a mainly female community and we started with the cynical observation that they would surely pick a male hero.
So: you need a game that has a recognizable plot line to it, but not one that allows much impactful choices by the player.
