6. ICO
It’s a sad game all around. Little guy ICO, singled out because of his telltale horns, gets deported into some faraway castle, as a sacrifice to the old gods (or the new?). But something goes wrong, Ico gets free and takes ghostly girl Yorda along for the ride.
Eventually there is a somewhat happy ending in there for them all, but stil they’re outcasts in a grey, drab, hopeless world. Even if there’s watermelons. Uh. Wherever those came from.
