These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
YMMV: Ratchet & Clank: Size Matters
Alternate Continuity: A lot of fans see the game and it's sequel as this, due to the lack of references in the Future trilogy and beyond. Into the Nexus confirms this.
Contested Sequel: Some fans consider Size Matters to be the worst game in the franchise, mainly due to Ratchet returning to his jerkass roots and Otto's plot to extract intelligence, which Clank considers "pure evil", to be quite narmy. Not to mention the amount of glitches in the game, and Luna being a difficult boss.
Into The Nexus confirms that Size Matters and Secret Agent Clank are non-canon.
Moral Event Horizon: Luna may have been a jerkass when we found out what it really is, but it crosses the line for good when it tries to KILL the heroes with farming equipment.
And Otto is soon revealed to be over this line when Qwark finds out that the technomites killed his parents.
Narm: Clank's line: "That is pure evil". Of course, Otto Destruct's plan to extract intelligence from people using an army of clones isn't as evil as many other villains, especially in the canon games.
