Meh, I played the first one and Future for the Xbox. I think it's an O.K. series, a little too overrated IMO. Lol @ one of the comments suggesting to use the Wii balance board to skate and the Wiimote to tag. It's like if they put Tony Hawk on roller blades and gave it a neo punk makeover, the OSTs were always spectacular though so I'll probably pick that up.
I played Future, and loved it. It wasn't all that complicated like Tony Hawk, but it had an awesome art direction, great music, and was simply fun. Nice, plain, fun.
You'll notice that it's these types of games that always seem to leave to true legacies. I wish developers would pick up on this.
