I usually hesitate to simply post sales news, because that's what LewiePs are for. But in the case of RPS space-strategy favourite AI War I will make an exception. It's 75% off with all the expansions included on Steam. That makes it $4.24 or £2.99 or €4.24, and that's a fine price for such a huge slab of spaceshipular cleverness. A chunk of the money raised will be given to charity Child's Play.
