Perhaps my favorite thing about Bastion is how it tells this particular story. The entire game is told in the past tense from the perspective of Rucks, who acts as narrator and is the sole human voice heard in all but a few instances. Rucks's deep and slightly western sounding voice doesn't just match the setting, in many ways it defines it. Rucks's personality and dry sense of humor as he explains what's happening on the screen adds so much to the gameplay, and it's immensely helped by the fact that the player's actions determine much of what is spoken. Many times in the game I'd try some weird weapon combo or try playing the game slightly differently just to see what would trigger a reaction from Rucks and to hear what he'd have to say on the issue. Rucks also expands upon the story in ways the Kid would never have known at the time, such as telling an elaborate tale about an old boat in one level and many of the major enemies have stories Rucks covers as well. This adds a lot of life to the world and made me keep wanting to jump on the next skyway to see what would come next.
The music of Bastion is incredible. Featuring some of the richest tracks I've ever heard. Both the instrumental tracks and the few vocal tracks work perfectly to capture the feel of the world and the game. In addition to the music and sound design, Bastion features a fantastic visual style taking place in an eccentric, vibrantly colored, and well-detailed world. In no way does Caledonia ever look like Earth, yet the game makes constant connections between the past and the Kid's present, making the history of these people matter.
