Does everyone here know about Kamiya's Bayo 1 commentary let's play? He basically plays through the whole game (playing well for someone who has to talk at the same time!) basically reminiscing about the development process. He drops little trivia tidbits (he tried to name the enemies in alphabetical order in the order they're introduced in the game) as well as developer insights (even placing a few hidden consumables into a level last minute would require an overhaul of the area because of tight memory constraints). Very insightful and very addicting.
Why didn't I know this existed? Thank you for posting this!
