There was nothing special about the storyline in TFU, nor was anything else all that amazing, not even the over-hyped physics engine they never shup up about.
Yet, inexplicably, it was a lot of fun. I played through it multiple times, always enjoying smashing my way through level after level (with the exception of that stupid Star Destroyer thing).
It's exactly the type of experience I have my consoles for, and I will certainly pick it up.
