The idea is based on alternate history. So it would be like historical fiction. (Think Assassin's Creed)
What next, I definitely want to make it myself, and all I know is Java.
So should I make it as an app or for desktop like Minecraft, it would probably be free or very cheap.
I know this isn't much information, I suppose I could say that it would be WWII based alternate history…
Also, what genre should I make it, I was thinking strategy, but I don't have any ideas for game mechanics in that area, but no other areas sound like they could fit with the theme.
Any suggestions are welcome.
