My main disgust. I have to spend $20 more for a invasion system that I've been waiting on since day 1 of playing this game
Wtf? All games get added with new features, major updates, and overhauls. Look at other popular strategy games like Stellaris, Endless Legend, etc which have gotten new features and complete overhauls. The game has been more than complete for ages, and now when they feel like they can expand on it, you complain? Next time, don't buy a game ever until every single new feature and expansion has been released.
"Disgust" is laughable. If you hate it, move on with your life and drop the $20 elsewhere
