Just note that it's flexible funding, which I don't think Kickstarter has, so they get the money whether they reach the goal or not.
The new alpha is pretty good and they are paying Redfox, who is quite impressive, to do a lot of important stuff to make the engine better.
They have 7k of 160k already which isn't bad but not amazing either.
If 0AD can eventually get a solid part one beta release this could bring attention to a lot of other open source games since people will have to accept that a non-commerical game can be superior to commercial products.
Hell even Spring doesn't have as much potential as 0AD.
