Who know. I will make something in future and it will be cool to listen about some of people ideas or better to take some advise.
The best advice I can give is: make what you want to make.
In the past, I have tried to make several RPGM games. All of them, I gave up after spending at least 100hrs on each of them. These things are time consuming and difficult. Finding the right words, the right gifs, the right images-- that takes time. If your heart is not in it, then it will not be continued.
Even if you are enjoying it, taking breaks, weeks or months, is allowed! =)
Especially if you are addicted to, say, a certain Skyrim playthrough or something.
The post-apocolyptic world you made is one very sexy. I feel like if you made a game with a female protagonist who has to fend off the world, that would be amazing.
There are many games that are like this, where an over-the-top horny world exists with the girl being raped with storylines on the side-- which means there are plenty of authors to get advice from if things don't work! =)
Urban Gal, Bad Influences, After the Plague, Fucksome Road... to name a few.
Recently, Ghost Hunter has become my favourite because of its amazing features.
Ultimately, I love this style of game where you go to the same place, but get different results.
That is my personal preference. It is what differs engagement for me, otherwise I'd just be reading a Visual Novel.
I look forward to seeing what you make, regardless of my preferences <3
