0Classic games cloned as open source

I’ve long been a big fan of Trans­port Tycoon and have been play­ing OpenTTD for many years. I recently thought I’d look to see if any oth­er clas­sic games have been sim­il­arly cloned, and it turns out quite a few have!

So far I’ve found…

• OpenTTD: Trans­port Tycoon Deluxe
• OpenRCT2: Roller­coast­er Tycoon 1 and 2
• Open­Fod­der: Can­non Fodder
• OpenRA: The entire 2D Com­mand & Con­quer series includ­ing Red Alert and Dune II
• Cor­sixTH: Theme Hospital
• Free­civ: Civil­isa­tion II
• Lin­CityNG: Sim­City 3000
• Wide­lands: Set­tlers II
