Parents should be ecstatic. Finally a safe game for their children that won't drive them mad with its inanity! Run to the store, folks, you won't find much better than this for your young kids. Although that's a little sad, actually.
Animaniacs Fans should run right out and grab this as well. It features all of the show's original voice actors, and a nice sampling of supporting characters. Not as wide as I'd hoped, but Chicken Boo shows up, so that's a pretty big plus.
Deaf and Hard of Hearing Gamers should be fine, the dialogue is subtitled, and there aren't any audio cues. They'll be missing out on the incidental dialogue and jokes, since nothing other than that first Buffy game bothered to subtitle them.
