I was a little surprised that Angry Birds appears to be not compatible with the Roku 3. Also, it appears that none of the other Angry Birds games (Seasons, Rio) are Roku 3-compatible. The new device does, however, include Angry Birds Space.
A search of the Channel Store on the Roku 3 (nice interface, by the way) for "Angry Birds" returns only the Angry Birds Space game, but none of the other three. And, all the other channels on my account showed up, except Angry Birds (that came with the Roku 2 XS).
Looking further, the Roku Website shows 49 games in the catalog. But, the Roku 3 Channel Store only shows 45. The four missing games:
- Angry Birds
- Angry Birds Rio
- Angry Birds Seasons
- Wheel of Fortune
Just thought this was worth mentioning, in case it impacts fans of those games.
