In stock first, then what you'd pay with any fee the shop's feed gives, then price. Commission never changes the order.

How to redeem it on Steam

Open the Steam app on your computer and sign in.
Choose Games at the top, then Activate a Product on Steam.
Enter the key and follow the steps.

Or in a browser: store.steampowered.com/account/registerkey

Steam leaves region limits to each game's publisher. If a key won't activate, the shop you bought it from handles it: Steam doesn't refund keys bought elsewhere.

From Steam's help pages, read 23 October 2026:

Regions, in the shops' words

Europe, EU, EU & UK, EMEA: Sold for Europe, and the shops' pages I checked say these activate on UK accounts. The platforms don't name the UK: Nintendo UK says to use a code meant for Europe, and PlayStation's terms ask for one from your account's country.
Global, worldwide, region free: The shop says it activates in any country, the UK included.
Region not stated: The listing names no region. At ShopTo, CJS CD Keys and Kinguin, the shop's own terms or every page I checked say these work on UK accounts; at Keycense they vary, so theirs never set a price here.

No platform defines these words: each is the shop's, so check the region on its page before you buy.

Questions

How much is Cities: Skylines?

On Steam, from £6.84 at Keycense (key, some ways to pay add a fee); on Xbox, from £19.74 at CJS CD Keys (key, no checkout fees). Prices checked 23 October 2026.

Can I buy Cities: Skylines from an official store?

Not now at the official stores I check: only key shops have it in stock, and each row says which region its key is for.

Will a Cities: Skylines key work on a UK account?

The prices I lead with are only from offers their shop says work on a UK account. Steam leaves region limits to each game's publisher. If a key won't activate, the shop you bought it from handles it: Steam doesn't refund keys bought elsewhere. Xbox says a code has to match your Microsoft account's country or region, and that using a VPN to get round it can get a purchase reversed or the account restricted. 3 listings name no region at a shop whose listings like that vary, so check the region on its page.

How do I redeem Cities: Skylines?

A Steam key goes into the Steam app (Games, then Activate a Product on Steam) or Steam's website, and the game stays in your library. Xbox codes are redeemed on your console or at xbox.com/redeem, and the game stays on your Microsoft account.
