We're excited to announce that we've fully migrated the Xbox Forums to their new home, here on the Microsoft Community forums!
As of today, going to forums.xbox.com will redirect you here to the Xbox area of the Community forums. We've moved all of your existing threads over so you can continue and start conversations with the new forums experience.
We sincerely appreciate the feedback you have provided over this transition and can't wait for you to check out the new Xbox Forums!
In order to fully complete the level, you have to play both acts (Act 1 being classic sonic and Act 2 being modern sonic). I wouldn't call modern sonic's levels junk at all - you'll be able to bare it if you've played Sonic Adventure 1 and 2. I have to say
that the last stage of modern sonic's levels is just annoying though.
