Well, I really hate pre-order bonuses and time-limited content. But, on the other hand, I really liked the first game from Owlcat, so I have preordered their second game. Somewhat, as an exception.

steam workshop will be later addition, while game will still have mod support at launch. I guess many early mods will be available in Nexus, which is good news for GOG users.

Pay £43 to be exploited as a beta-tester? No thanks. I'll wait until after it's fixed/patched, by which time it'll probably be on discount.

Deathloop wants $20 extra for a few skins and a soundtrack "sampler," so it's all relative. Hopefully the three expansions are better this time.

They sound good, at least, and could add up to 20 hours to the base game. Especially the epic-level campaign could be fun, like HOTU was.

Also, I find it kinda ironic that the most expensive edition of this game is the one with the most sales so far, followed by the core edition. The one in the middle (with goodies and without the SP) is a distant third here. :D

Eh, screw it, I might get the game after all at launch, it does look like a lot of fun. I still loathe those scummy exclusive pre-oder DLC tactics and the fact that there is no way to pre-load the game if you're using offline installers only.

What in the world does pre-loading a game look like with an offline installer? Isn't that just...an offline installer?

Pretty much, most of the time you only have to download a few more parts or an .exe and you're good to go, helps those with a crappy internet connection (like me) that want to play the game on launch day.

Makes sense really, if you care about the fluff you'll probably go all out. Also a big reason to get these types of editions is to support the devs, let's be honest.

So you want GOG to deliberately create broken offline installers with missing files, and then somehow make the missing files available later? I hope I don't have to explain why that's a bad idea, but even if it wasn't, GOG can barely cope with normal, unborked installers as it is; expecting them to manually fiddle with things to make that work is rather unrealistic, don't you think?

That's not how it works. They only give you 90% of the installer to download in advance (So about 24 GB right now) and save the last ~1.7 GB that can't be downloaded until release day. They've done it before. Offline installers are already multi-part chunked into 4 GB segments.

It's pretty easy.
As mqstout explained earlier, publish 90% of the installer parts and leave the rest out for release day.
At release day you just publisher another last offline installer part (or two) and you have the complete package, quite simple to implement this if you ask me.
Or give users every part to download and only 'keep' the last installer part that contains the .exe. At release you publish that part and again, you have a working installer.

That's how you 'somehow make the missing files available later'. It's rather simple to be honest.

For which game? On Windows, yes (for some reason).

At least Witcher 3. I'm pretty sure others.
Some reason: Numerous reasons. Better download-resume. Better management for people who do archives. File system considerations for compatibility. Yadda.
