Openage – Free Age of Empires 2 engine clone
It's amazing to see so many community powered open source projects dedicated to keeping old games alive (while also preserving the same look & feel these games had back in '90s).Along with the OpenMW[1], OpenRA[2], OpenTTD[3] and OpenRCT2[4] listed on openage's GitHub page, lots of others exist. To name a few:* OpenXcom[5] for X-COM: Enemy Unknown and the later Terror From the Deep games.* Nuvie[6], Exult[7] and Pentagram[8] for Ultima VI-VIII respectively.* GZDoom[9] (and various others) for running Doom, Doom II etc.* Freeciv[10] for running Civilization.[1] https://openmw.org/[2] http://openra.net/[3] http://openttd.org/[4] http://openrct.net/[5] http://openxcom.org/[6] http://nuvie.sourceforge.net/[7] http://exult.sourceforge.net/[8] http://pentagram.sourceforge.net/[9] http://forum.drdteam.org/viewforum.php?f=23[10] http://www.freeciv.org/
