Is Assassins Creed worth another go?

I was never that enamored by the original Assassins Creed. It certainly didn't deliver after being so massively overhyped.

Don't get me wrong, it looked fantastic, oozed atmosphere and was the first game to bring free-running/parkour to the masses but I wasn't too keen on the whole alternate reality "memory recall" storyline. Why do games add these little twists anyway (yes, Return to Castle Wolfenstein...I'm thinking of you. Your wartime elements were great...the supernatural parts, not so!).

Assassins was billed as a sandbox game but felt somewhat restrictive and linear. In all fairness, I didn't give it too much of a go when I first bought it soon after its release in 2007 but with news of the sequel emerging, I'm tempted to dive back into Altair's shoes.
