The sad thing is that 06 had potential.  It just was... uh... not very good.
And rushed.
And endless amount of loading screens.
And bullshit time travel.
And why are the maps so freaking huge?

This is coming from someone who can find something wonderful about each title in the series, Sonic 4 aside (because I couldn't play it with the 'little' speed issue when I tried the demo/free day/whichever).

(Yes, I'm a Sonic fan.  Favorite non-main title is Sonic R for some goofy reason.)
