Blue Shells are a sore spot for me (I mean come on! 2 Blue Shells AND Lightning on the last quarter of the last lap?)
This isn't to say blue shells are by any means easy to avoid. But it is a hell of a lot easier in MK Wii than it was in Double Dash.
I can only remembering escaping 3 or 4 Double Dash blue shells.
I kind of miss the old school N64 blue shell that hits everyone on the way.
