Well, I've been a musician for quite a long time, since I was little, and sometimes when I get spare time I'm torn between if I should work on playing/recording something or if I should do something with just computers (I'm actually not a hard-core gamer, many of the games mentioned on this forum I admit I'm not familiar with), although it is just more recently I've been doing things with sound FX and such. To address your question more directly, most of the work I do in my DAW is more music-related, only occasionally doing sound FX of some kind.
I've also just recently started programming my own home-brewed VST plug-ins, with the VST 2.4 SDK and CodeBlocks in C++. Before I started that, I heard programming your own VST FX was very difficult and took serious programming, but I've actually found with my skills it isn't that bad, for me, at least with the types of plug-ins I'm into. It's going a little slow though, as making plug-ins is a side project.
