Just wondering if there might be an upcoming compression of this game?
For what I normally see, that will hardly be the case.
Most compressions are made on games that uses regular archives of audio (mp3, ogg, ...), images (jpg, png, ...) and videos (mp4, mkv, ...).
Games like this one don't use so much "pre-made" media, and most of what we see are... "real-time rendered objects"? I actually don't know if the name is correct, since I'm not a pro, but maybe we can say it's close enough.
So, in the end, a compression like the ones we see on other games around here would be too much work for too little results, since the most we could do would be making the sounds a little worse, and trying to find a way to reduce textures without breaking the whole game.
