The "one account per installation" idea is really bad. If I were subscribing to this game and paying a monthly fee (like you do most MMORPGs) then I could understand it, but this was not the case, and certainly not how EA promoted this game.
I really REALLY want more than one account for this game. I play it. My 6 year old son plays it. And now my partner wants to play it. We've seriously got to all share the same account and have all our creations linked to the same username??? That's just ludicrous! We'd all like to have our own creations linked to our own usernames. Forcing me to buy more installations is just not on EA! Please please please sort this out guys. It's a tremendous game, but if I have to fork out more money so that my whole family can enjoy it on more than one account I will seriously reconsider playing any further.
