I've read that the Steam version doesn't have achievements, yet. That's feature parity by non-implementation. ;-)

This is true.

And I'd prefer GoG to get the release right, rather than "fast," if I have to choose between the two.

The problem is, we shouldn't have to choose.

Apparently, from what little I've read, the issue is that someone at 3DRealms provided the files to GoG too late for this to happen, but gave the Steam folks the game files well in advance.

Which, IF TRUE, reeks of illegality, frankly. Not that I expect any one to deal with it in those terms.

The main, real difference between GoG and Steam is where they're located for their main operations. Steam is US-based, as is 3DRealms. GoG is eastern-Europe-based. Poland, I think, isn't it?

So, perhaps the delay has something to do with export issues? That's the only legitimate justification for the delay I can see. And by "legitimate," I mean "in conformance with the law," not "it's reasonable."
No, it's not. I went to the released product page, and downloaded the installer. Installed it. And it's still the "preview campaign."

And Galaxy didn't provide an "update" either.

If you still can't access the full release, you should contact GOG support. I've been playing version 1.0 since I made that post, and the website officially posted about the game releasing here: https://www.gog.com/news/release_ion_fury

By all means, you should be able to access it, so some weird bug must be in place.

Thanks for replies everyone

Was up half the night last night playing this, was well worth the wait, enjoying the heck out of it so far.

It finally came up in the early afternoon, for me. Central Time Zone, USA.

Anyway, got it now. So... "yay!"

Enjoy!

GOG released a game four hours later after official statement from 3D Realms. How unprofessional!

This is still the preview release. Guess i'm going for a refund and buy it on steam instead....

You should have both. If not, that either means you own only the Bombshell Digital Deluxe Edition (in which case you're only supposed to see the demo) or something went horribly wrong and you need to contact GOG support.

The download page provides version 1.0. The full game also isn't available through gog galaxy

Just install it through the offline installer (1.0 is correct) and Galaxy will run it without trying to change the version.

Well, i did. But as i said this isn't the final release. It only has only one chapter "Night on the Town" and once you finished it, a splash-screen shows up with some teasers for the full version X)

If I go through my Profile, all I see is the demo in my games, probably that's what you did.

But gog.com/account has the full game. Go there.

V1.0 @ 94MB file size? Thats the one i installed.

That's the full release, yeah. You can only access the first chapter because you didn't unlock the rest, unless there's an uncommon bug you're encountering.
