So I am new to GOG, I jumped here as soon as I saw the DIno Crisis bundle and wanted to ask how often or if GOG does patch their games. I saw one for DC 1 but I am wondering if they'll fix DC 2, as I have no issues with the controller but the game won't let me remap the menu/pause buttons. I also found out the trex is silent in the first encounter. I got the Rebirth mod working for DC1 but from what I heard DC 2 is a bit more tricky. Any suggestions or should I wait a bit?

No one outside of GOG can tell you for certain what they will or will not do with regards to patches, but my experience has been that they update games relatively frequently when issues are discovered. I've got about 35 games in my GOG library, and I would guess that every week or two I see at least one of them marked as having an update.

Now, I don't use the GOG Galaxy client/launcher since my gaming system is not online, so there may even be updates I've not noticed.

As far as the Dino Crisis games, with the big deal they're making about them becoming available and being inducted into the Good Old Games Preservation Program, I fully expect them to be watching these forums and looking for things to fix, such as the ones you've mentioned and others have reported. It's in their best interests as a business to make sure high-profile older games like these are widely playable so people can see that the Preservation Program label actually means something.

Thank you for the info, I downloaded galaxy after I downloaded the games as I wasn't sure how it works with updating games offline. I assume if there's an update I just delete the game and re-download it if patches are in the new version for the offline version but I need to research how the galaxy way works.

I'm not sure exactly how Galaxy works for updates, but most of the updates I've seen for my games are released as both an updated install file that is for the current version, and also as a patch file so you don't have to re-download the entire game if you have a previous version.

None of the games in my library currently have an update notification, but I went through them to see how they'd handled patches so I could give you accurate information. The best example in my library is Galactic Civilizations III. The game itself is almost a 9GB download (not including DLC), which would be a pain to download and reinstall every time there were an update, but right below the install files are the last four patches GOG released. So anyone who has one of the previous four versions of GalCiv3 that GOG released would only need to download the patches if they're using the offline installers like I do. Much more manageable and a timesaver besides.
