Additionally, some games are not available here from other vendors. Example Dead Space 2. Neither Impulse nor Direct2Drive sell it to Norway. Probably as punishment because we've twice said no to join the EU. Steam does.
BTW: I won't buy it for the nearly 50 euros they are claiming - I can get it cheaper in retail stores here.
