Description:I took inspiration from two Tumblr posts which diverged from the same source in that annoying "how are you meant to follow all this" manner that Tumblr tends to encourage. I rather like that (the description was "Mostly Harmless", this is a bit more accurate).
Humans are bipedal, clannish and omniverous, with incredible endurance capabilities. Humans evolved tool use in order to better hunt their pray, and would pursue much larger animals for days if necessary in order to bring it down and then eat it. Modern humans still have a strong fight or flight response but any threat an individual cannot handle will be met by a larger group working together to defeat it with overwhelming force. Humans have been known to eat items they know to be indigestible, simply to prove they can do it, and use toxic substances as seasoning to flavour their food.
Modern humans have formed geographic nation states with a strong basis in historic tribes. These states compete with each other, sometimes to the extent of going to war, while still cooperating on other issues. Differences over religion, resource use and even the correct way to cook a particular meal are still used to justify aggressive acts, and these wars act as spurs for further technological progress.
We're working on the final coding for the next stable release (0.4.5) at the moment, test builds for Win and Mac are normally released weekly here and, well, a bughunt is ongoing.
It's a 4X space exploration and conquest strategy game, taking inspiration from old classics like Masters Of Orion but definitely not trying to ape them, although it's nowhere near finished, it's definitely very playable, if you like strategy games generally it's rather fun, more details on the FreeOrionWiki, but that's always out of date (every time I update a bit we do more work).
