Which digital format of Subject 13 should I buy for PC? An Account or a Steam Key ?

The account format is cheaper but has a more complicated activation process compared to a simple key or code.

If you’re looking for a simpler and safer activation process and don’t mind paying a bit more, we recommend buying the Steam Key format.
