Shadow was a good game, not great but it wasn't terrible, the story is absolutely terrible, random aliens that have never been mentioned before ever appear and you find out THEY created shadow? Not only that but the whole multiple ending things is terrible, the only ones I liked are the one where Shadow decides to destroy earth to bring justice to humans and the one where he kicks Sonics ass and says he's the greatest hedgehog.
I dislike the whole black arms thing and also, in SA2 Gerald created the Eclipse Cannon to destroy mankind but then you learn he created it to save it? Either he made the eclipse cannon before he went insane or it's a major plothole, I also hate the final ending, shadow decides to forget his past and maria? I hate that, he's supposed to be getting revenge for Maria not saying "KTHNXBAI *throws picture of her away*"
And the 06 story was even worse, I can't really say that the storybook games' stories are that bad, but they're not good either.
As for Unleashed, i'm *censored.3.0*ing tired of Eggman summoning great monsters to try to rule the world, it never bodes well for him (Chaos, Shadow, Dark Gaia, the list goes on) I'd much rather see Eggman as the main bad guy not some random monster from the center of the earth that only appears once in the game.
I also dislike chip, that should've been Tails being his partner like the old days not some Navi/Chihuaha inbred.
