There's a ton of competition among set-top box manufacturers, and it means everybody wins: in the last three weeks Western Digital and Boxee have delivered big updates to their boxes, and now Roku owners are getting theirs in the form of four new games. Pac-man Championship Edition, Galaga, Storm in a Teacup, and Angry Birds Seasons are now available in the Roku Channel Store, and can be downloaded to any Roku 2 box for $4.99. Of course, in order to play you'll also need the $29.99 Game Remote, which comes bundled with the Roku 2 XS but not other models, so your nostalgic Galaga play will come at a bit of a price.
