A Sephiria Steam Key — also known as a CD Key or digital code — is the official activation code you redeem on Steam and keep in your library permanently. From €8.80 (-41%) at G2A, Steam Account format · Cheapest official key: €10.69, 28% below the €14.79 Steam price · 5 verified stores, 9 offers in stock · Updated 01h 02min ago.
Sephiria for PC starts at €8.80 at G2A, 41% under the €14.79 of the official store — but that is a shared account, not a key of your own. If you want a key tied to your own account, the cheapest is €10.69 at Gameboost.
That €8.80 already includes the GCKG2AR8J6B coupon, so apply it at checkout or the store will show you a higher price.
Supply is thin — 9 offers from 5 stores — and thin supply keeps prices steady rather than falling.
That puts it 17% under its average of €14.79 since 2025, so today is a better entry point than most days of its life.
That €10.69 key is at one of its best prices.
Worked out from 467 daily records of the Steam Key for Sephiria across 6 stores. See the full price history.
The price does not include each store's payment fees. The percentage is measured on the store price, without coupons, because that is how we record the history. The analysis only counts Key offers. Shared accounts, Steam Gift and physical editions stay out, because they are not the same product and their prices move differently.
With the shared account at G2A you log into an account that already owns the game: it is the cheapest route, but it never becomes yours and the seller keeps the credentials. If they ever lose or change them, you lose access.
The key at Gameboost costs €1.89 more, but you redeem it on your own account and the game stays there for good. That is the difference between renting and buying.
The 2 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
7 of the 9 offers work on US — the Global ones plus the ones issued for your own region.
