Thanks for all of your input! It has mostly seemed to me that if I was going to do games, I would have to really want to do programming. That's why I've mostly ruled it out at this point. I wouldn't compose something and have someone else write the score. I wouldn't outline a book and then have someone else write it for me. To me, doing game development without programming seems rather similar. It's like trying to create something without actually speaking the language. That's not impossible, but it's not something I really want.
Man, being a musician in games sounds like a nightmare. Fortunately, when it comes to music I have a good amount of options. One of the things that I started looking at more recently is something I do naturally but that I feel there's always something to learn about. That's really important to me. I don't want to be doing something where I feel behind on the basics, but I also don't want to do something where my interest in it is so narrow that I feel like I've done everything I want to do in a few days. There are also certain things in terms of lifestyle that I'm looking for.
The reason that I've come down to music at the moment is it seems to offer most of them. I can play piano and sing at a high intermediate level. With a little more training I could do both of those at an advanced level. With a little more training than that I could be writing orchestral scores. I already have a good ear both for listening and creating. So it would offer me a lot of opportunities in the sense that I could do anything from piano accompaniment, playing in a bar or hotel, doing arrangements for a small orchestra, or composing for a film or a game. There are a lot of others besides, and I like the versatility of that. There's a lot I can learn, a lot of experiences I can have, and I'm not dependent on one small, probably unreliable, corner of the profession to make me money.
The list of game types is really helpful. I've gone in a number of these directions. I did push my way up to about 40 hours each in AI War and Crusader Kings 2. I know that's not much in terms of really grasping it, but the thing I kept coming back to was, even though I felt that they were great games, I just didn't have that sense of wanting to come back and play them when I wasn't. I've had similar experiences with a lot of great tactical games.
You mention experience games though, and it's funny as I just did a run through of my book collection to try to find the common trait that has maintained over going through thousands of books and keeping only a few. It turned out to be subjective experience. The ones I liked best in any field are the most insightful subjective commentaries (Feynman in physics, Sacks in psychology, Pelton in journalism, Tim Burton in film, and so on). It did occur to me to look for the most experiential games at the time, but I wasn't really sure where to look. My first thought was something like F.E.A.R. which may not have been quite as experiential as I was looking for.
I think I've avoided experiential games to a degree because I hated even the idea of them when I was younger. I wanted something with "gameplay." Now every time I play something with "gameplay" I find myself frustrated with the repetition of it and just want to have something intriguing to interact with. Minecraft I felt was too open for me because in that instance I wanted more of an experience, but when I play a lot of other games I start feeling like I've "experienced" the entire game in the first ten minutes just because I know how similar the rest of the gameplay will be to that. So that could definitely be an avenue to try. I'll have to look into that more.
Anyway thanks again for all your help, and it wasn't too depressing.
