Name Site License Notes
Delphi Doom Sourceforge GNU General Public License
Quake to Delphi Sourceforge


GNU General Public License Sourcefoge is the active one. The old-site appears to be quite dead now. Though the source code can still be downloaded.
Quake II Delphi (Quake 2 Delphi) GNU General Public License
C-evo Public Domain The game is inspired by Civilization 2 game. It was spotted on the forum back in 2009. The engine used is not the original Civilization II engine. So as long as graphical resources are different, it's quite good TBS engine.
