So trust me - I feel really, really awful about doing this, especially so early in the game - but honestly, at this point, I don't really see any other option but to call this off.
I had a bit of an epiphany a while ago: I actually don't enjoy running world-spanning games of this sort with 30+ players and like twice that number of polities total. After a very short period of time they truly become a drag, and I have immense respect for GMs who can work through that. I personally just don't have the patience to. The reason I keep feeling the urge to run these sorts of games, I think, is the truly immense amount of fun I had in worldbuilding. And what kept me going beyond that was engaging with players who helped add to that world, through your stories and even just random chat conversations. I truly, genuinely, want to extend an immense thank you to everyone who did that - every single person who posted fluff in this thread was fun to read, especially christopher_sni - and I also want to extend a huge apology for pretty much completely wasting your effort.
Furthermore, that one update took way more time and effort than I had anticipated. It had nothing to do with the gameplay mechanics, which were fine - it was simply that, a lot of days, I would come to my computer and open the requisite things only to find that I just didn't have the energy or the motivation to do it. The game wouldn't have been sustainable like that. I tried to make it interesting for me by adding space and nukes and stuff like that, but only ended up shooting myself in the foot by placing those off in the distance. Additionally, I realised that there were about half a dozen other things I told myself that I wanted to do with my free time in 2017 that running this game would have made utterly impossible.
Furthermore, I also shot myself in the foot again by making the start of this game excruciatingly slow. That's also about the pace it would have gone had it continued. That isn't something I'd want to do to either myself or to all of you lot.
With that in mind, I think this is the last time you'll see me run a world-spanning game like this (though I'm open to co-GMing at some point)
Again, I'm really sorry, and I feel terrible about wasting everyone's time, but this game simply wouldn't have been sustainable in its current state, and it was better to than to let me, the game, and more importantly everyone else involved, all suffer.
