The Steam Sumer Sale is now on, and will run until July 22.
Current highlights include the Portal 2 and Total War: Shogun 2 franchises being 75 per cent off, Legend of Grimrock at 60 per cent off and Call of Duty: Modern Warfare 3 at half off.
On top of that, community choice sales – where users vote on deals - is updated every eight hours.
EA recently claimed such sales "cheapens your intellectual property."
"If we thought having a 75 per cent sale on Portal 2 would cheapen Portal 2, we wouldn't do it," Valve retorted.
