fishbaits: If they knew there was an incoming patch, they would've most likely (if had any sense) said as much. There was zero mention on steam, devs twitters/fb etc nor on here that there was going to be any more patches.
Ok so you just assumed then, and you assumed wrong, as more patches came later and found their way to the offline installers as well.
Also, considering how new a game Shadow Warrior 2 was (and still is)... wouldn't it have been quite odd if it wouldn't be receiving more updates quite soon, especially due to its multiplayer aspect? Or did you feel that one previous update fixed all existing problems that the game had, and there was no need for another update?
Most likely GOG was aware of another incoming patch, if they had made their mind already to wait for the next patch. It is quite possible that the publisher had communicated this to e.g. GOG (esp, if GOG had asked that), even if the publisher had not communicated it to all end-users. That is just common sense.
fishbaits: Also, seeing as you bring multiplayer into this, it would've also meant no one could play steam - gog due to different patches too.
I already explained that I'd always personally use an auto-patching client for modern multiplayer games which need "constant" updates, for exactly that reason you mention. The game depends on everyone using the same version, so auto-update is very important. Also, more and more GOG games' multiplayer part requires Galaxy anyway, so...
My interest to the offline installers receiving updates too is more related to archiving my games, and there it matters less if a patch comes e.g. a week or even a month later (depending on its criticality too), as long as it comes.
fishbaits: Yes, it did get patches later on, but that's not the point at all.
That's the whole point. Your complaints seems to be some kind of moral principle thing, I look at it practically.
Wake me up when GOG really refuses to update the offline installers anymore, and the only way to get further updates is through Galaxy. Then I start caring.
