How much does X4: Foundations for PC cost right now?
X4: Foundations for PC starts at €2.51 (€2.62 with fees) at Difmark, 74% under the €9.99 (no fees) 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 €4.45 (€4.65 with fees) at Difmark Digital Keys.
That €2.51 (€2.62 with fees) already includes the Gocdkeys coupon, so apply it at checkout or the store will show you a higher price.
With 32 offers across 18 stores there is enough competition for the price to move, so the gap between the cheapest and the rest is worth checking before you buy.
That puts it 25% under its average of €7.09 since 2019, so today is a better entry point than most days of its life.

Is it worth buying the Steam Key for X4: Foundations now or waiting?
That €4.45 (€4.65 with fees) key is at one of its best prices.
- Those €4.45 (€4.65 with fees) are 74% below what it usually costs, measured on the store price.
- 16 stores sell the Steam Key at the same time, and with that much competition the price moves almost daily.
- Not counting today, only 52 days out of the 2,324 days on record were this cheap or cheaper; the lowest it has ever cost is €4.00.
Worked out from 4,915 daily records of the Steam Key for X4: Foundations across 28 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.
Which X4: Foundations format should you buy?
With the shared account at Difmark 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 Difmark Digital Keys costs €1.94 (€2.03 with fees) 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 9 Steam Gift offers are pricier than the key and leave more room for error, because they depend on the region and on Steam friendship.
Can you activate X4: Foundations in US?
24 of the 32 offers work on US — the Global ones plus the ones issued for your own region.
Why is there such an expensive X4: Foundations offer?
One listing is worth ignoring: the Steam key that Greenmangaming has at €49.99 (no fees) is more than 19 times the cheapest offer and is not what this game costs. The number to work from is €4.45 (€4.65 with fees) at Difmark Digital Keys.
