This is only the beginning of a story, but it could prove to be a very interesting story if it bears out. I think it already contains instructive lessons for game development and design.
On the left, Dwarf Fortress. On the right, Goblin Camp.
I hope you know about Dwarf Fortress, the very complex roguelike-lookinglike fantasy world sim / citybuilder. From a development perspective, DF is a very long-running obsessive project coded by one guy, Tarn Adams, who makes more money than I do (not difficult) entirely by donations from his fans. I admire Tarn’s goals and his creative freedom which lets him indulge his whims – I wish I could do that. I even had fun playing some Dwarf Fortress until I explored most of what there was to explore. It was sweet while it lasted, but I grew tired with the tedium of a very rough user interface and tedious gameplay.
