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.
Is Fighter a naive idiot with occasional sparks of genius, or is he a brilliant mastermind lulling everyone into a false sense of security? Strangely enough, offered by Fighter himself. Further supported here. (The Socratic Method is a method in which you ask questions and debate to get answers instead of just finding someone who knows. Also could reference the well-known Socrates quote, "The only true wisdom is in knowing you know nothing.") Oh, and here.
Arc Fatigue: The last arc, which spent several months of what was essentially one continuous conflict which kept changing, then spent about 4 months on the Light Warriors screwing around to try and gain levels to face the final opponent. It then becomes clear this was completely intentional to make the ending all the more anticlimactic.
Neutral Good: Fighter, type 1 (passively good towards friends, though he has no issue with helping strangers).
Lawful Evil: Thief, a combination of type 1 (easier to become ruler of the world by exploiting the existing system) with a bit of type 4 (imposes ridiculously harsh rules and abuse the hell out of Exact Words).
Neutral Evil: Red Mage, a combination of type 1 (amoral) and a little bit of type 3 (indifferent to the good/evil conflict).
Crazy Awesome: A majority of the cast. The main characters are defined by this trait. However, special mention goes to Ranger, a supporting cast member. Ultra special mention: Sarda is probably the god of crazy awesome, as shown by the twostrips immediately after the above example:
Genius Bonus: The LaGrange Terrace joke in this strip. For those unfamiliar, Lagrangian points are the five locations in space where a small object can be in stationary orbit relative to two larger celestial bodies (such as a planet and its sun).
Older than You Think: Many concepts which some believe originated in 8-Bit Theater are actually much older, and appeared because Brian Clevinger was part of Final Fantasy Fandom. For instance: the Black Mage being non-human (this came from Final Fantasy IX and there are clues to this effect as far back as Final Fantasy III), White Mage being a woman (this was a common perception among fans), and the grouping of four White Mages defeating Chaos (winning the game with this party is an old test of mettle for players).
Rescued from the Scrappy Heap: The original game's version of Black Belt was despised by players as a useless class. Here he is so beloved that many fans refused to accept his death.
Black Belt: Life is funny. You start out with limitless potential, but time is always shaving away the possibilities. Every choice you make is the choice not to do a thousand other things. Whatís important when all is said and done is that you made a difference. Your choices and everything undone, have to mean something. Otherwise, what was the point? Iím lucky that way. My path was already there. I had only to walk it. I often thought even if no one knew of the good I had done with my life, it didnít matter. That it was done is all that counts in the end. But Then I died.
White Mage: Black Belt?
Black Belt: And I hadnít gotten to do any of it yet.
Fighter's reaction to Black Mage being killed by Lich:
Fighter: Black Mage? Get up and yell at me. Black Mage, get up. Please.
Weird Al Effect: Some of the things that people believe to be true about Final Fantasy I is stuff that was invented by Clevinger rather than things that were inherent in the original game, such as Fighters being dim, Black Mages being sarcastic, etc.
The idea that White Mages are women was present long before this comic, but it was cemented here.
