watch that please.
i, personally, am looking very forward to this game. the game looks like it will provide endless amounts of fun and should sell pretty nicely, for those of you concerned about sales and junk. the only game it looks to compare to is the original adventure.
you have to understand that sonic the hedgehog 2006 is a tragic work of art. we were given awesome trailers and stuff before the release, and then the game came out, and it completely flopped. it's failure is most likely linked to sonic team being rushed by microsoft while also making the very foolish decision of firing its entire debugging team. quite possibly the only redeeming qualities of the game are, in my opinion, the music and the story. we were given a lot before the release, only for our hopes (well, at least mine) to be shattered upon the game's release.
this game, however, we are given (as you can see in the video i presented you with) clear gameplay. i'll admit, i was iffy about the werehog myself. after watching that video and seeing the werehog rumble his fists around in an awesomely cool cartoony manner, my jaw literally dropped (this reaction happened again when i watched the video for a second time, mind you).
also, sonic and sonic the werehog are the only playable characters during the story. there will be side missions that are 100% optional, and other characters might be used in those missions. so far, tails, knuckles, amy rose, and shadow are confirmed to make appearances somehow in the game. once again, if they were to be playable though, then they'd ONLY be played in the side missions, which i will repeat are all optional--they aren't necessary to beat the story of the game.
