I would ask Paradox, to make the Galaxy more alive. Trade ships, civilian ships, moving about. I would also love, if paradox added some galactic WMD. I really liked, how a rival superpower was very agitated about me building a circle world somewhat near their borders. They assumed I was building a weapon, and demanded to inspect the facility. I wish I could have built the very thing they suspected I was building. I would like more events, including more silly events, or just weird ones, like a star trek kind of mixed bag of all kinds of stuff happening, just for flavor. I don't want every event to have a huge impact, or immediate impact on a civilization, but they do make the galaxy feel more a live, and more mysterious. I'd like more planetary super projects, or wonders. Like this super expensive building project to upgrade a planet capital into a super artistic/monumental/scientific center at great cost. More improvement types on the planets in general. More colonization events. More art variations for ships of different species. A mechanic where a small, or even a single system civilization, how ever hard to do, is a viable strategy. Like a great center of galactic trade, or culture. More treaties types, as well as deeper protection and alliance mechanics. I loved the Utopia DLC, great job Paradox! Just more stuff like that! Thank you all, cheers!
