Yes, but I would differentiate further, in that a developer formulates a goal before he goes ahead and develops it.
I have never formulated a goal when creating music. I just sit on the keyboard and am always surprised what emerges after a while.
THAT is the key difference.
Ofcourse I can formulate a general direction like today my mood is for classical music, I want to use harpsichord and strings... etc... let's see where it leads me.
Music is "played" not developed.
I play while creating music.
One major goal of mine is to enable the development of playing.
I want people to be able to play games in which characters such as bards can exist and in which a bard is a type of character that is typically known for his her or it's ability to play and/or sing and/or recite (perform) songs and/or poems.
So development of the ability to play is important for the development of the kind of immersive environments/games I am trying to develop.
In order to develop free open source such games, I need free open source play-techniques and methods for playing free open source songs or instruments, so that, for example, a bard can be portrayed playing an instrument and/or singing a song.
The number of people who want the ability to create such games is not as important or driving really, even if you insist on being able to appeal to a huge audience in order to get lots of advertising revenue, because even if only one person in the entire world produces such games, and thus only one person in the entire world perceives the importance of the ability to tinker with the underlying details that make a particular song sound like the singer has a sore throat, or sound like the singer is female, or sound like the singer is pronouncing the lyrics with a particular accent - pronouncing it the way a certain region's inhabitants pronounce that word for example - and so on the end result game the development of which is enabled by having full access to as much as possible of the underlying mechanisms and instructions might end up being massively appealing to the masses...
