I am glad there are some games running on Linux, but the games I own on GOG sadly don't work on Linux, and they are

dungeon keeper
dungeon keeper 2
Vampire Bloodlines
Phantasmagoria

I hope one day they will run on Linux, but we will see.
Are there any games you own on GOG that you wish run on Linux?

those games dont have a linux version.

Dungeon Keeper uses DOSBox and Phantasmagoria uses ScummVM, so those at least should be trivial to run on Linux.

Are you suggesting that these two do not run as desired with Wine (Windows compatibility layer), or, are you simply seeking native ports?

For years, I have been playing the first installment through Wine (via KeeperFX).
Wine can also be used to run the second game (personal experience). Uncertain about Phantasmagoria, but, Vampire: The Masquerade - Bloodlines supposedly runs well with Wine.

Dungeon Keeper, Dungeon Keeper 2 and Vampire: The Masquerade Bloodlines are all supported by ./play.it.

I play them on GNU/Linux (Debian Sid) on a regular basis.

They already work via Lutris as does 99.9% of my GOG library.

I wonder if Play It is actually Italian or they chose the site just for the visual pun...

Not to be that guy, but a visual pun is an image. Sometling like this:

A bit of a stretch, but, like this? "play-it"

To each their own, but I never got the appeal of open-source Steam clones.

./play.it is here to fit the needs of people who do not want to use an all-in-one launcher/client managing their games collection.

--- The core dev team is from France, but we got contributions from all over the world (with Eastern Europe being well represented).

The choice of the "it" TLD was just for the pun ;)

You shouldn't have any problem running most of the games from GOG catalog using Wine by manualy install everything or by using a software like Lutris or Heroic Game Launcher

French. I ought to know that /s
