What are some of the retro games you have bought outside of GOG, because they were not (yet/anymore) available here? And why are they worth it to buy them off-site? Feel free to include links to the wishlist!

I only have Aliens vs Predator (1999) (Steam). I bought it because of apost on RPS (€2,99). I didn't regret it; it's a genuinely scary game at times! There's a similarly intriguing post about the second one too, but I don't think that one's currently available to buy anywhere online.

You can find a lot of nice old games (most even DRM-Free) which are not aivailable on GOG at GamersGate.
A few examples:

Freedom Force
Gunlok
Aliens vs Predator Classic 2000
Harbinger

Same goes for DotEmu:

Wars & Warriors - Joan of Arc
The Sting!
Cold War

Both GamersGate and DotEmu often have those games on sale dirt cheap for prices from 0.75€ - 2.49€.
