Just decided to play this on a whim yesterday and yeah it's not good. Most levels are just the same sort of fetch quests; the only meaningful difference is what the collectibles look like. This is not helped by the fact that the titular Home for Imaginary Friends serves as the setting of every level which, surprisingly enough, makes for some repetitively boring gameplay. At least the game's rather short.

That said, I think the show's imaginative (heh) art style and character designs are portrayed pretty well here. Mac and Bloo also control pretty nicely--that's more than I could say for other licensed games of the era! All in all, it's far from the bottom of the barrel, and if you're a fan of Foster's (like me), you might even get a kick out of seeing a handful of episodes being adapted into different levels. Not really worth playing other than that though.
