Assassin's Creed got it done right. While there is not a map editor (maybe later?), the story content is there. Placing the editor access online via web browser allows for the cross platform and doesn't eliminate the consoles. I watched the
official trailer and
the developers seem very up beat and positive about this editor. I am not a big of the AC series, I tried one of them with my oldest son (the one where you are a pirate) at his place on the Play Station. My hope is they are very successful and shows Cryptic how they not only missed the boat, they drove it into the iceberg and sank it.
By the way, whoever made the decision to burn the Foundry to the ground... bad idea!
