$10 for SotS 1 and 2. 1 includes all the bonus content. First 1000 people, according to the page on GS.http://impulsedriven.com/id/flashsales/spotlight/?AFFID=eml_i081612_09&CID=eml_i081612_09
At this point, the game is getting pretty close to what it should have been at release. I'd say it's worth 10 bucks for both at this point.
To confirm from one of my gift purchases for this, you can activate this copy of SOTS2 on steam. Uncertain on the SOTS1 version included in this.
