Not every campaign is of an equal level but the Specter and Shovel campaigns are good enough to justify at the very least a high 9 but the rest probably gets the 10 just for the sheer level of content. Full transparency I bought this when the package was around 15 bucks on 3DS and I think around 30 on every other console I own this game on. 40 might be a bit much of a splurge but the package is still incredible.
