Brothers: A Tale of Two Sons is a great step in the direction of games as art. It tells a very interesting narrative in a tight amount of time (around 5 hours, leisurely), doing a great job of combining the interactivity with the story.
Speaking of the story, it's the main draw of the game. The ending is must-play, while the rest of the game is very good. The emotional journey is the key driver in Brothers. While I do think the bulk of the story could have had more emotional elements throughout that led up to the ending, the ending still was able to provide me with a positive impact.
As such, I definitely recommend a playthrough.
