Unlike most (if not all) previous Scooby-Doo titles, this one comes in wonderful cel-shaded goodness. Looking back, it's a bit odd that we haven't seen more cel-shaded Scooby games since most titles that are based on a cartoon license these days are pretty much automatically given this graphical treatment.
Anyway... Scooby and the rest of Mystery Inc. all look great. Each detail from Scooby's spots to Fred's orange ascot (that sounds like such a dirty word) comes across loud and clear. Scooby's various costumes also appear nice and everything from his Robin-Hood costume to his Kung-Fu get up are brightly colored and pleasing to the eyes.
The gang's voices are comprised mostly of actors who have participated in the recent cartoon movies like Scott Innes (Scooby and Shaggy) and Frank Welker (Fred). Those voice actors who haven't had much on-screen experience with the Mystery Inc. detective agency still do a great job of imitating the original cast.
