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: Mutants & Masterminds
Broken Base: As with every other RPG ever written, this happens every time a new edition comes out. For example, the forums have been in a mild uproar over the recent release of 3E, particularly with the fact that points don't go as far as they used to in a lot of places.
Ultimate Showdown of Ultimate Destiny: A common pastime on the official forums; generally takes the form of rolled-out combats between characters, usually with an accompanying story, rather than simple arguments over who'd beat whom.
