Steam is having one of those super good publisher sales. This time round? It's Square-Enix stealing the food out of your children's mouths with a fairly brilliant sale on most of its best titles.
What's on sale? Practically everything. Almost every Final Fantasy game has about 50% off at least, meaning you can pick up Final Fantasy VII, for example, at $5.99. All the Thief games have 75% off, as does DLC. The Thief Collection, which includes the latest iteration released in 2014, is just $11.24. That's pretty phenomenal.
Perhaps the most incredible deal is the Just Cause collection, which features both Just Cause games and all the DLC for $3.79. That's just... ridiculous. I've paid that for a cup of tea.
The list is extensive and the sale is good. Head here, knock yourself out.
