I propose a question; How might one complete a 'canon-compliant' playthrough of games 1 and 2? By this, I mean to create a sort of gameplay video or movie roleplay thing. I'm not sure how to clarify further.
The less fun part would be trying to establish continuity of Knack's powers and physical integrity. How to succinctly describe this? If we're making a video we can cut out the parts where we die, but if he goes from scraggly and lightning-streaked to totally prim in an instant, it breaks immersion. And then there's the sunstone stuff and gadgets and yeah. Does he still have the shockwave in the second game? I haven't played it and haven't seen a player use it. Also what difficulty should be chosen for this?
Anyways, the more fun part is playing as Knack. The lab level in the first game is a tutorial for the player, but for Knack, it's a demonstration (at least how I interpret it). It's fun to act theatrical about it, then. Very interesting are the opportunities for mercy that come up. Would Knack take them?
The ultimate goal of such an endeavor would be to figure out how Knack would play his own game.
