Hey goggers. I'm trying to compile a list of every current gog game that have gone open source. The Build engine is open source, for instance. The code to Jagged Alliance 2 is out also. Same with Freespace 2.

Anyone care to help me with my list?

Really? I was sure Unreal 1 wasn't open source.

Hm well don't take my word for it. Far Cry for sure though.

Uh, no. Cryengine 1 is not open sourced either.

The ones I know of are:

Enemy Engaged: Commanche vs Hokum (which integrates with Apache vs Havok, so you more or less have the source code for that one too).

Descent + Descent 2

Duke Nukem 3D

Freespace 2

Beyond Good and Evil and Prince of Persia: Sands of Time share the same engine and source code, but they never were released from Ubisoft due "contract reasons". So, both games fall out of the category.

Call to Power 2

Blood 2 has opensource, Blood 1 doesn't and is still requested by the fanbase.

Also, I think Duke Nukem and all the other Apogee games are open source.

Sure. This is the most complete list I'm aware of : "source available" and "open source" games which were before closed source.

(PS: sorry for necroing)
(PPS: here is a community wish about making more games source available via GOG http://www.gog.com/wishlist/site/obtain_source_code_for_games_where_possible )

Warsow. Well, not "gone" open-source, it was OSS to begin with.

EDIT: Oh, damned necro.

Conquest: Frontier Wars is suppose to have its source released at some point.

At one point Uplink: Hacker Elite had its source code available as part of the GOG package, but I guess that changed. (It appears the soundtrack isn't available anymore, either. :P)

Thanks for "Conquest Frontier Wars", some weblinks or reference pointing to such an announcement?

Uplink is infact a pretty interesting case, Introversion plainly sells the source code of their games for 45$ under a very strict non-open-source license. http://www.introversion.co.uk/store/
As far as I'm aware of, the only game company doing this.

Thank you! I've been trying to find this site for a while and I couldn't remember the damn name.

Arx Fatalis is open source, I believe.
