This is a really interesting list. BTW, don't forget to click through to https://en.wikipedia.org/wiki/List_of_commercial_video_games_with_later_released_source_code https://en.wikipedia.org/wiki/List_of_commercial_video_games... IMO, some of the most important/interesting games on this list are (in no particular order): * Colossal Cave Adventure * Zork * Habitat * SimCity * Doom and its various incarnations. * Quake * Balance of Power * Civilization IV -- Wow, this one was a surprise to me! I'm gonna poke around with it some. * Civilization V -- Also a surprise. * Elite * Unreal, and its various incarnations * Eliza * Oregon Trail * Akalabeth: World of Doom * Empire (paging @WalterBright). I remember spending a lot of hours on this one. :-) * Pac Man * Pole Position * Wizardry III Maybe I've missed a few, but these are the ones that stood out to me.
