And by 'awesome space games' I'm referring to stuff like Alien Isolation, EVE Online, Kerbal Space Program and dozens more. Alien Isolation is $16.99 and it's one of the best AAA games of last year. Easily.
The sale is on the Humble Store and it's fairly extensive. Plenty of titles are knocking 80% off their normal RRP. Impressive stuff. I'd get on it if I were you: there's only 14 hours left in the sale.
