I bought the game. Later, a platform for building modified versions grew around it. Even later, another platform with pricetags on the modified versions appeared. All along, the game that I've bought has been gaining features for free, although I'm also free to be a traditionalist and load+play the game that I originally bought. None of this seems like something that's harming me.
