Darkspore on sale for 40 percent off its normal asking price. From now through 4PM PST / 7PM EST on Thursday, June 16, the PC-only title is going for $30, down 20 bucks from the MSRP. Steam is also offering an eight-pack of the multiplayer-enabled game for $90, normally $150.
Our review said that Darkspore was all right, but had "a lot of room for improvement." Now at least one way to improve it has been addressed: make it cheaper.
