Now that the week is well underway, it's a good time to take stock of the video game discounts that are live and handpick the best of the bunch. We've got all the best deals on fantastic games for PS4, Xbox One, Nintendo Switch, and PC in the pages ahead.

What sales are we picking from? We've scrounged through some of the best deals available this week at retailers like Best Buy, Amazon, and GameStop, as well as on digital storefronts like the Microsoft Store and the PlayStation Store. We've got big discounts on games like Mario Tennis Aces, God of War, and GTA 5.

Then again, some of us don't have to pay for select games at all. If you're a PlayStation Plus or Xbox Live Gold subscriber, you can get August's batch of free games on the applicable systems. PS Plus members can pick up games like Mafia III, Dead by Daylight on PS4 and Bound by Flame and Serious Sam 3 BFE on PS3. Xbox Live Gold members owners can grab Forza Horizon 2, For Honor, and Disney Epic Mickey 2. And if you have an Amazon Prime account, don't forget to grab your seven free PC games from Twitch this month, either.

We have to pay for the rest of the games we want this week, so let's get to the goods. Here are the week's best deals on games across all platforms.

Mario Tennis Aces (Switch)
Help Mario and his cohorts smack the dust off of all the tennis balls in the Mushroom Kingdom in this recent Switch release, on sale for 25% off.

God of War (PS4)
A more mature Kratos visits the realms of Norse mythology in this action game. But don't worry, he still eviscerates plenty of enemies, be they mortal, beast, or god.

Call of Duty: Black Ops III - Zombies Chronicles Edition (Xbox One)
With Call of Duty: Black Ops 4 landing October 12, now is a good time to pick up its predecessor. The Zombies Chronicles edition comes with the base game and includes eight remastered maps from Zombies modes in previous games.

Star Wars Battlefront II (PS4 and Xbox One)
After a spotty launch last year, this game has improved greatly in the months since. If you were reluctant to pick it up before, maybe these sale prices will push you over the edge. Just make sure it's not into a Sarlacc pit.

Grand Theft Auto V (PS4 and Xbox One)
With nearly 100 million units of sold, it's a surprise anyone has yet to purchase this blockbuster. Even so, it was the number 3 best-selling game of June and PS4's top-selling game last month. Maybe this deal will help move even more copies.

The Legend of Zelda: Breath of the Wild (Switch)
Nintendo rarely puts its first-party games on sale, but right now anyone with a Switch who hasn't visited Hyrule can do so for $15 less than usual.

Tekken 7 (PS4)
Anyone looking for a fighting game that's mechanically complex enough to keep you coming back for a long time can pick up this one for just $20 on PS4.

Jackbox Party Bundle (PC)
For the next two weeks, PC gamers can pick up a Humble Bundle containing 10 Jackbox and You Don't Know Jack games for just $12. Not bad if you have people over and are looking for something to do.

The Crew 2 (PS4)
Ubisoft's latest cross-country racing game lets you change your vehicle from a car to a boat to a plane with the press of a button. What's not to like about that? PlayStation Plus members get a bonus discount on this one.

Mario Kart 8 Deluxe (Switch)
Sure, it originally launched on Wii U, but this version of Nintendo's latest racing combat game comes with all the DLC, improved graphics, and new content (including a battle mode that isn't terrible). Pick it up this week for 25% off.
