Maybe I missed the logic train....So you can compress 25GB down to 9GB...and, then patches are 9GB there after.....because why?

Are you talking about the the entire game as an offline installer being set at 4GB blocks? Because that is a completely different thing than stating all future updates must be around 9GB....for, some random reason. After the unpacking of the game, how would it make any sense at all to require a 9GB file just to update something.

Oh wait did you work for Microsoft or Apple?

¯\_(ツ)_/¯

If the game ends up being 25 GB instead of 9 GB due to weaker compression I'm really less likely to buy it. Just saying…

Hypothetically, it depends on how many changes are made in that patch, typically with a highly compressed archive even a small modification made to that binary can result in a much higher patch, as apposed to a lighter compressed archive. We have been working with the compression though and we are pretty confident that at day 1 release the game will weigh in at around 10-15GB instead of 25GB. Once we are happy with the change and it doesn't effect performance in any way, we will update the system requirements on the product page prior the release.

Not trolling you by asking, why not just use that standard archival compression with a simple unpack and over write? If using Galaxy is streaming small updates....it seems pretty off the the mark for huge patches to be used for simple overwrites. It sounds like entire sections of the game being replaced or redownloaded for no explained reason why.

As in why would a patch replace so much of the base game at all to require 9GB patches? I figure if the product is that poorly managed....thats a red flag chief.

Game seems neat though. Rez games are a few I may actually play on consoles.

Not trolling at all, it's a genuine question that I'm happy to answer.
So the game before we made the change to compression packs the files into lightly compressed seperate archives, but we've made changes that packs it into one highly compressed archive. and upon testing patch changes the difference is small in size. Sorry for any confusion caused. We will change the system requirements to reflect the new size.

Humor everyone, if a bundle is on the table. Keep them separate. Especially for offline variant. This is to cut size for people that just want the new version. While making the customers happy if they want one or both.

We will explore the best ways of offering choice to customers with GOG.

Regarding size of the game, it's now at 10GB which is much more accessible than before.

A teaser of one of the areas in the game, Blue Moon, which we have just been revamping, graphics wise!
We can't wait for the release in September!

I've been looking at the difference between this and the original and I have to say that is quite a make over.

It's definitely not what I expected after I looked at the original release date!
Nice

I would like to support this request, because it is interesting, to experience the evolution.

I have reached out to GOG so hopefully it can be bundled. Since the game now only takes up 10GB as a base of space, the original game is 3GB making a total of 13GB bundle for the two games.

Does GOG assign you a fixed total storage quota for hosting your game(s) on this store? If so, you would now have plenty of space. ;-)

I can't confirm any specifics due to NDA.
