Are you eagerly awaiting the day when Pokémon games are fully polygonal? In a way, I am, and in a way, I'm not.
Regarding the former, for instance, I really like how the folks at Game Freak have incorporated polygonal backdrops into the most recent Pokémon titles. Regarding the latter, though, I'm quite happy with the sprite-based Pocket Monsters themselves.
All that said, I'd be perfectly content if the polygonal Pokémon that are sure to show up in a future installment of the series look anything like Flickr user Filip Johannes Felberg's LEGO-based creations (above).
