Inspired by this thread:
Might migrate this later to "Deep Thought", but at present I'm looking for game titles that we can confirm have had their source released. These are the titles that have the greatest likelihood of surviving multiple processor and OS changes. For example, since the DOOM source was released, it has been ported to numerous systems that never had the original release. Also, source ports allow for the possible enhancements of the game's interface, so new ideas can implemented while preserving the original gameplay.
This list is nowhere near complete...In fact it will only start with a few titles that I can recall "off-the-top-of-my-head".
Battle of Britain (Rowan)
DOOM (DOOM II, Ultimate DOOM, etc...)
Duke Nukem 3D (v1.5: The Atomic Edition)
Enemy Engaged: Comanche vs Hokum
Ken's Labyrinth 3D
Mig Alley (Rowan)
Rise of the Triad (R.O.T.T.)
Star Control II (The Ur-Quan Masters)
If you know of a source release (not necessarily a port), let me know, but please give some kind of reference to back it up.
