I have a duplicate key for that game, so I am giving one away for free. I played this game already and I think it was good: https://store.steampowered.com/app/746850/Cloudpunk/
To get the key you have to submit your email here: https://www.humblebundle.com/gift?key=ZWyyc2Su7BNBpr7z You might have to register too, I don't know.
First come - first serve.
If you haven't seen any of the trailers or gameplay for it yet, it looks like the city is going to be a lot more dense in terms of architecture and even people. In between the buildings you'll see power lines, AC units, skybridges, all other manner of junk and clutter. I think it looks absolutely amazing so far.
