Insomniac and Naughty Dog - A noteworthy observation of their franchises?

[Words Of Wisdom]

Insomniac pumps out a metric ton of Ratchet and Clank games. They always have one in development because they can basically reuse most of the game material, spruce it up, and the fans will eat it up.

Much like Koei and Dynasty Warriors.

I don't know how you can compare 2 games (Resistance 1/2) to 12 games (R&C) and think the focus is changing. Also there is another R&C game (A Crack In Time) scheduled for release in Q4 this year on the PS3.
