Welcome!
A few hints, so you're not disappointed later:
Supporting GOG, CD Projekt and most importantly DRM-free is fine, but it comes with a few caveats:
- Some games are "abandoned" by devs. Which means Steam versions are up to date, versions here are not. GOG staff is trying to remedy this as good as they can, and sometimes they succeed, but there's only so much you can do... without getting a hold of the person in charge that involves straps, a towel and a few buckets of water. Steam is just by dimensions larger and therefore more important to most devs.
- People with blue text are "the locals" (meaning GOG staff). You can even chat to them, they are very friendly most of the time.
- People with yellow text are devs. They sometimes turn up here for a Q&A when a game is released.
- DRM-free means, you can download all installers simply via per browser and install them on any machine you like. No need to be online for that. You can play every game offline too (except for Gwent) and that indefinitely. Just be aware that many games installers come with the Galaxy client included - if you just want to back up your games, just download the installers without it.
- GOG is a small company from Poland. In the past there was no support on weekends - now they have a skeleton crew at least. Just don't expect a fast answer from support when it's Sunday 4:00 AM in Warzawa...
- Don't mind the site bugs... For every thing they fix here, two other things break...
- The community... well it used to be better, and it was really worse recently. But IMO it's still one of the most friendly and open international communities around, at least for gaming websites. Just ignore the trolls and don't fall for scammers.
