User Rating: 10 | ICO PS2
It is Ico, a boy of only 14, who has had the bad luck of being born as a horn bearer, a personified bad omen and he therefore has been sealed away by his own people in a place with no return, a mystic castle without exit due to magically sealed doors.

No exit? Not quite:

Still puzzled by the new sight of things Ico par hazard encounters and rescues Yorda, a fragile female, who appears to be some kind of elflike princess, formerly locked up in a cage floating high up in the air.
It is Yorda, who has the power to unlock the magically sealed doors.
As Ico will soon discover Yorda is being hunted by dark creatures, Inklings.

Defenceless as Yorda is, it's again Ico's turn to prevent her from getting captured and sucked into the darkness she initially escaped from. They share the same fate, and it is fate that brought them together, now it's their turn to trigger the wheel of fortune.
This is the beginning of an unforgetable adventure, a boy with horns and a mysterious princess, a wordless friendship without hope, on their escape from the clenches of death.

One step, two steps, three steps....

On the run jumping, fighting, climbing, swinging and swimming-since Eidos Tomb Raider the standard-repartoir of a new-age adventurer, however ICO offers innovative and unique technics:

When Yorda is close to Ico it is possible for him to take her by the hand and drag her around. If Yorda waits for him in a distant place Ico has the opportunity to yell for her so that she comes over. Yorda's movements are determined by her fear and fragility, only the touch of Ico's hand grant her the security and protection needed in order to move on without hesitation. When she is unable to reach a certain location, it is up to Ico to help her either to find another way or by the means of physical support, be it a path-blocking bolder or just an hand reached out to encourage her in risking a jump.
