Calling all PC/Mac gamers. Steam has launched a fantastic “Autumn Sale“, where different daily deals has some of the biggest titles discounted by as much as 80%. Today’s deals, which started about 30 minutes ago, include Monkey Island Special Edition bundle ($5.09), Total War Mega Pack ($12.49), Fallout Vegas ($4.99) and much more. Not all games on sale can be played on a Mac (assuming you’re living a Windows-free life), though you can browse the Mac section to see which are compatible. The Autumn Sale runs through the Thanksgiving weekend (ending Nov 27th), so be sure to head on over to Steam over the next few days and check up on the latest deals.
