They both have aspects I find good and bad. For instance the way they gave a personality to the Guardians in R2 was something I sorely missed in RR. The free-roaming is good too, but I wish they had combined it withthe Hall Of Doors somehow...that wasreally awesome. I also liked how Teensies get more part in R2. The level revisions are good, adding quite some more to the gameplay.
Bottom line: I think both games deserve credit, since both are pretty good on their own. Whether which is better or worse, I think that mostly relies on how individual players see it. 83
