Steam Summer Sales are a great time to pick up top-notch PC games for rock-bottom prices. Case in point: There are nearly 20,000 games on discount during Valve's 2017 sale, and nearly half of those are under $5.
But a lot of those games are junk. So we spent hours sifting through the Summer Sale’s stock to find 15 great games that cost less than a fiver. These may not cost much, but each kicks a lot of ass.
