Whereaminow25: Also want to know if we will be able to make an account at sporepedia also :)
You should be able to, as long as your cdkey is added to EA account. Registering from in-game menu is unfortunately not working.
More detailed instructions can be found here:
Whereaminow25: So the game requires cd keys to even run then?
no, only for online content (upload / download of creations)
other than that game is perfectly playable offline
