So, what do you think? Are you dissapointed that the sequel was cancled? Happy since the overall concept wasn't any good? Or something else entirely?
I personally am dissapointed (since all Rare seems to do now a days is stuff for the 360 avatars and games that involve them), but with the way the game was going, I guess that in a way it's a good thing that the game was cancled (Jo isn't the main playable character? Blech!).
