Steam Summer Sale: The biggest discounts

The annual Steam Summer Sale is ongoing, and Polygon is here to help the spendthrift gamer find the best deals. We're rounding up the biggest discounts, best steals and cheapest choices out of the hundreds of discounted titles.

If you're looking for the best games for the best value — say, at a price drop of 75 percent or greater — these are some of your safest bets. Remember: All prices are good only through July 4 at 10 a.m. PT.

BioShock and BioShock 2: $3.99 each (80 percent off)

Picking up these two games now is especially smart, considering you'll get their remastered versions at no added cost when they launch in September.

Crusader Kings 2 Collection: $39.99 (75 percent off)

Grab the grand strategy game and all of its DLC — that's 43 different items in one bundle.

The Talos Principle: $9.99 (75 percent off)

This unique puzzle game struck our reviewer as a perfect combination of Portal and Myst. It only surprised us further from there.

Saints Row Ultimate Franchise Pack: $12.49 (75 percent off)

Get five games and a wild amount of DLC with this set. You'll save nearly $60, to boot.

Mass Effect Collection: $8.74 (75 percent off)

Note that this lacks the controversial third entry, for whatever reason. Still, it's a great way to get into the series ahead of its fourth outing, Mass Effect: Andromeda.

Civilization 5 Complete Edition: $12.27 (92 percent off)

Brush up on your Civ skills ahead of the sixth game, out later this year.

The Sims 3: $4.99 (75 percent off)

It's The Sims. You should know what to expect — or, if you don't, it's only $5, so now's the time to find out.

Psychonauts: $0.99 (90 percent off)

If you haven't played this cult classic by now, there's no excuse to keep holding out on it at that price.

Brothers: A Tale of Two Sons: $1.49 (90 percent off)

This charming, pretty game is heartbreaking without being overly sentimental.
