I like the way Ubisoft decided to split the content to present and promote online the upcoming release of Assassin's Creed. When you first get on the official website you can decide how you wish to discover the game: you can either enter the "experience" website or the "regular" game site.
If you go for the "experience" site you will get a cool video(game) exploration, where you have to click the right key at the right time to further unlock content. On the contrary, if you select the "regular" site, you'll find all the usual info and goodies (gallery, downloads, forum) but also an interesting series of videos developers' diaries. Probably it's just a question of wording, but it stays smart and it creates the right expectations for each choice.
The agency who did the site is Diplomatic Cover.
