I agree that the actual variation you need to put in for a gender variable MC is minimal. Like you said "Personalities aren't gender-specific". But it makes me so excited that you are putting as much thought into it as you are. While I don't need everything catered to me specifically and it can actually be really good to experience a romance from a different point of view, I am very excited to see a MC that is more relatable to myself in one of your worlds.
I think I expected it to be more work, and in some games maybe it would be. One thing you learn fast is that every game is very different, so what applies to one may not apply to another. But that's why I like to experiment. It helps me work out what is actually feasible for me and what I enjoy writing.
It's fun to work on different things and, honestly, customisation as a feature is a lot more accessible to small devs than it was a few years ago. There are a lot of tools available now to help us do things like recolour art or add in pronouns in a simpler way. It opens up a lot of possibility.
I hope Wil is an enjoyable character for you in the final game. They're fun to write sometimes (they can be such a gremlin. ha ha). 🤣
