I've mentioned this a couple of times on Facebook and Twitter, but Infamous Adventures (who remade King's Quest III a few years back) have finished their re-make of Space Quest II.

IA's remakes are really well done, and written to run on modern computers. They're also free, so if you enjoyed that era of point-and-click adventures like I did, click on the link and download SQII.
