Anthony, the editor in chief over at XeNonX wrote an interesting article comparing developers Insomniac and Rare. In particular he focussed on the Ratchet & Clank and Banjo Kazooie franchises. In the article he talks about how Rare seem to have been influenced in their decision to make a new Banjo game because of Insomniac's growing success with the Ratchet franchise. The article does go in favour of Insomniac but he makes a well thought out, logical argument though many would see it as bias.
From The Article:
"The concept behind 'N&B' sounds quite cool actually, the idea of making your own vehicles allowing you to solve things within levels does intrigue me, but will it work? From all accounts it works well but has a rather steep learning curve. Something which Ratchet, for the most part, doesn't have. Surely platformers are there to cater for the masses? They are meant to appeal to kids and adults alike, something that Insomniac can pull off very successfully. It's simple and effective and keeps people playing for ages. I don't see the same thing happening with Banjo."
