I'm going so far as to give it 5 stars! It was 4-4.5 until the last 2 where he goes over The Ball iOS conversion, such great valuable information I highly recommend this DVD.
I'd love to see him (or whoever does it for/with him) do Enemy/Bots/AI the only thing "missing" from this series. I say "missing" in quote b/c its not really missing just something else I'd love to see a series on.
