Prices are approximate and updated constantly. Review all the information at each store before buying. Gocdkeys is not responsible for possible price differences.
Summum Aeterna for Xbox One starts at €6.71 at Difmark, 66% under the €19.99 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 €19.99 at Microsoft Store ES.
That €6.71 already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
Only 2 offers across 2 stores carry it, and thin supply means the price barely moves.
That puts it 16% under its average of €7.99 since 2023, so today is a better entry point than most days of its life.
What you can actually buy today: an Xbox Key from €19.99 at Microsoft Store ES, which you redeem yourself and leaves the game on your own account and a shared account from €6.71 at Difmark, where you log in with the seller credentials instead of owning it.
The shared account at €6.71 undercuts the key at €19.99 by €13.28, but on an account the game stays tied to credentials the seller controls; for €13.28 the key is yours and nobody can take it back.
All 2 offers are Global, so the code redeems on any Xbox account no matter where it was created.
Critics put it at 75 out of 100, though there are only 12 reviews published so far.
There is no third-party key on offer today, so the choice is between the shared account at €6.71 at Difmark — cheap, but the game never becomes yours — and paying the official €19.99 for a key on your own account. Either is defensible; just know which one you are picking.
