I actually really enjoyed the old-school, frantic, speed blurring action segments of Sonic Unleashed, but the Werehog levels were annoying, slow, and clumsy beat-em up breaks between the action that ruined the game for me.

Yes, you are the only one who would support a "saga of downloadable Sonic adventures." For such a big fan, I'm surprised you misspelled Sonic in the title. Also, I probably would have bought this game if there was no Werehog.

The 'filler' stuff is pretty much there to lengthen the gameplay experience within the 3D incarnations, and to also keep up with the demand for longer, more complex games. I honestly think that people would have enjoyed the Werehog stages more if it was Knuckles, and instead of super stretchy arms, Knuckles would glide across platforms or something similar.

Honestly speaking, who here would love a Sonic game that was just the daytime stages of Unleashed? Nothing in between?

I think they could probably extend the daytime stages if they varied it with levels that focussed more on platform or combat between all the running. The Shamar stage had some nice platforming bits where you had to slow down for them, for example jumping on moving platforms across spikes etc. That was very reminiscent of older Sonic games for me, so if they included more of that, things that slowed Sonic down, then it would extend the daytime stages a bit more. Course, they would need to tweak the controls a fair bit too, as Sonic himself is rather slipperly at times.

Just daytime stages, and Ill be won over.
