I've spent so many hours tinkering with Skyrim and other games before developing my own game. I think a part of me who likes to spend hours and hours doing mundane tasks breaking code, creating something new, and testing to make it work helps a lot with game making.

Sounds like depressionGame Development is better powered by Disappointment.
So if you think all games here are trash and developers are doing things wrong and you can do a better job yourself that would be better motivation than just liking something and being inspired by it, although that is also a legitimate way.
Being Disappointed would also mean you are sufficiently Different enough and that can help you out to stand out from the sea of other projects.
Of course the actual results might not be as special as you think, but this is more about the Motivation to get you through a Project.
The Good thing about Porn Games is there are a lot of Niches and Fetishes that you can use to be Disappointed by.
