Maybe I'm double posting over here ( I've tried searching for it but couldn’t find it. ) and if so; 'Sorry!' and if not; Let's all share the games you've bought so far on GOG.com.
I'll start:
Interstate '76
Caesar III
Septerra Core
Sanitarium
Divine Divinity
Lionheart
Diciples 2 Gold
Sacrifice
Fallout Tactics
Fallout 2
Gorky 17
Heroes of Might and Magic 3
Arcanum
The Pandora Directive
Freespace 2
Decent 3
Painkiller
Kingpin
Beyond Good and Evil
MDK 1
MDK 2
Messiah
Oddworld Abe's Oddysee
Beneath a Steel Sky
Arx Fatalis
Chrs!

Very much double posting. This is the oldest one I found, but there have been others:

Also, lots of people have a LOT of GOG games. I have more than 70. I'm sure as hell not going to list them all. And I doubt anyone would want to read a thread consisting of massive listings of the same games over and over again.

See, that's why GOG needs to add an option for making your game shelf publicly accessible. Why have that feature if you can't show it off to anyone?

Indeed. That is one of the most often wished-for features on the site, I believe. They've said they have a major site update underway, so one can always hope it'll be included in this one.

I hope they inform us beforehand, instead of springing a surprise like that. I'm afraid I'll accidentally get my monitor and keyboard soaked white.
