Thanks for replying.
I know this is your game, so please take my suggestion with a grain of salt, but shouldn't you have some semblance of a design? "Making a civ like game" isn't really a design. I've attached what I use for dumping game ideas into, which I find really useful in starting me in a direction when working on a project. It's a GDD in the most simplest form, which will help solidify an overarching design you want to pursue. Cuz from experience, without something like this, your journey will be a lot tougher. Having something written down creates structure, a plan, and gives you a list of tasks to put ticks next to (the systems and mechanics boxes).
Anyways, use it leave it up to you, I'm not telling you how to make a game. Just a suggestion from a game dev.
