Sweet! Does anyone have a list of high-quality open source games like this?
(Subjective interpretation, but something like, "I couldn't believe it's free, I would have paid for it anyway.")
The Free Civ and Free Colonization games are good. Brogue, Nethack, DCSS are good if you like roguelikes. OpenMW is a totally open source reimplementation of Morrowind, so that might fit the bill.
I know it's a very niche domain, but I feel this way about Lizard.

OpenRCT2 is a reimplementation of RollerCoaster Tycoon 2.
Just like its cousing OpenTTD which is a reimplementation of Chris Sawyer's Transport Tycoon.
Luanti aka minetest
Widelands as a settler clone
My first reaction was exactly that; I can't believe it's free!
