One of the greatest and most influential strategy games is available for less than £10 on Steam. If you're a PC gamer looking for something that will keep you busy for months on end, then you can pick up the excellent Age of Empires 2 Definitive Edition for just £9.99. While Age of Empires 2 Definitive Edition typically retails for £14.99, you can grab a code for the game from CD Keys for just £9.99. After purchasing the Age of Empires 2 Definitive Edition from CD Keys, the retailer will send you a link with the code that can redeemed on the Steam store. Steam codes can be redeemed in the wallet section of the website/app. After visiting the wallet page, select 'Redeem a Steam Gift Card or Wallet Code' from the options on the right and input your code.

The Definitive Edition contains a boatload of content, including multiple campaigns, game modes and lots more.

This includes The Last Khans expansion, complete with three new campaigns and four new civilisations.

That's on top of co-op gameplay, a Battle Royale mode and even a consistently updated Scenario Editor for creating your own missions.

Other improvements include 4K HDR visuals, as well as a newly enhanced soundtrack. It's even playable on Steam Deck.

"Explore all the original Campaigns and the best-selling expansions like never before," reads the official description.

"With over 200 hours of gameplay and 1,000 years of human history, improved experiences await.

"Head online to challenge other players in your quest for world domination with 35 different Civilisations.

"You can also experience new Civilisations and Campaigns with the Lords of the West DLC! Recent updates include a Battle Royale game mode, ongoing support for the Scenario Editor, Quick Play for easy social games, enhancements to the game UI, and more!"

If Age of Empires 2 isn't your thing, then Steam has a number of discounts available for a limited time only.

This includes a sale on the entire Dark Souls franchise. Indeed, Dark Souls Remastered is down to just £17.49, which is a steal for such an important game.

The underrated Dark Souls 2: Scholar of the First Sin is reduced to £14.99, while Dark Souls 3 costs £19.99.

It's probably worth purchasing the Dark Souls 3 Deluxe Edition for £29.99, which contains the two expansions available with the season pass. This includes the Ashes of Ariandel DLC, as well as the must-have Ringed City expansion.

Other games currently on sale include Detroit Become Human, Alien Isolation, Stardew Valley and Monster Hunter World.
