It is not a big deal. It doesnt have to be. Its just a small mod with a small change that some people apparently wanted for their experience. They didnt demand to change the game. I dont see problem with choosing pronouns, but I also dont see a problem with changing pointless stuff in your game.
Every game has bugs, that is not really what a ‘finished game’ is about. Its more about consistently working features, delivering what you promised and working on fixing things you know arent working correctly.
Of course the ground itself needs some kind of abstraction, there is no actual computing in the real numbers. Thats not the kind of grid OP is talking about though, they mean a grid where a character uses up a single tile.
How would it be easy? Please elaborate how steam would go about investigating OPs private life around the day of purchase and gather actual proof of them not going to the netherlands.
