Atleast not yet, and the buddy keys arn't even active. Either buy the game, get a buddy key when they become active, or wait 6 months to a year for a possible trial, never know, there may never be a trial.
Just buy the game if you want it. Make sure you can run it though. I would explain in long paragraphs why you should, but I'm tired of typing. Look in the other AoC threads =P
