CIG founder Chris Roberts offers more details in his latest Letter from the Chairman, which also outlines the game's $27 million stretch goal. Much like the previously achieved $23 million goal, the $27 million target will allow the dev team to expand alien spacecraft, only this time it's the Banu instead of the Xi'an.
"Even though we've fully funded the base game, every extra dollar helps to make the experience better," Roberts writes. "The content we talk about in these stretch goals isn't 'feature creep;' it's elements we've been building and planning that will be all that more impressive with additional resources. In essence, you're putting things we've already discussed for the future into development now."
