I left out day 2 of the Steam Summer Sale because I thought there were only low quality games offered. It´s little bit late but the Day 3 offers are still up and there are at least some games that are of high quality and which you can get up to 75% off…

Age of Empires II HD
Dragon Age: Origins – Ultimate Edition
The Elder Scrolls V: Skyrim
The Elder Scrolls V: Skyrim – Legendary Edition

You might want to open the main Steam page to see all other offers, but be fast because there are only around three hours and a half left for the Day 3 offers. But the mentioned games above are good deals, so be fast if you wanted to play one of the games.
