Cloudpunk was good but I wouldn't classify it as fun. It's one of those games that would have been better as a movie because it's gameplay was average at best. I hear there's a sequel coming out which I hope is better since I really liked the setting of the game.
On another note, I've never thought of giving away extra keys online before. I might have to do that with some of my keys.
Giving away keys is always a nice gesture. Keep in mind to not share the key in a post, though. There's bots created for Reddit that will look for keys, I wouldn't be surprised if something similar is available, or soon will, for Lemmy.
