release several games:

I don't have any.

I do this for fun, so I do what I think is fun or worthwhile. Some days I'm in the mood for bug-hunting, some days I want to optimize, some days I want to add new features or levels.

What helps me is that I have a pretty good idea of what the final game should look like. So all of this unstructured work still is towards a common goal.

And the only structure for having that idea of the final game I have is notes. I just write it down. I often don't even look at the notes, but I found that the process of writing things down helps me structure it.

Would this work for an MMORPG with 7 factions and 200 interwoven storylines? Nope. Does it work for reasonably complex projects? It has so far.

So ask yourself if you have not enough structure - or if you waste too much effort on writing docs and not enough on writing a game. I always spend as much time as possible on the actual game, not on stuff around it.

Caveat: It does mean I have a pretty large "games graveyard". I find that ok. There's very often something from abandoned games that I can use in later games. Some UI I did, some sub-system that worked well, some code that I can re-use, etc.
