5. Bastion

Developed by Supergiant Games, Published by WB Games

The flagship effort from fledgling studio Supergiant Games tasks you with creating a new world from the rubble of the old, though it's not quite as simple as that. Each chunk of said new world it is collected through arduous isometric action-RPG gameplay. There's always something coming along to knock your efforts back a pace or two, yet each level literally falls into place as you traverse it, as if the next stretch doesn't exist until the echoes of your footfalls reach it. Bastion is about the uncertainness of the future, melancholy longing for the past, and the futility of all that's happening in the present. You really have to play it to understand.
