Plot is a literary term defined as the events that make up a story
What are you trying to prove by linking to pages where the first sentence says that I'm right?
Well you could try reading the whole thing, but if you only read first sentences, then I've
bolded it for you.
Alright, I'll explain it, here:
PLOT is a term used for working with a story's actions and progression, the nice chart on the wiki page explains it pretty nicely.
CHARACTERIZATION on the other hand is something that is tied purely to character development. Sure, characters develop as the plot moves along, but the two are viewed separately. Generally, characterization splits characters into groups like dynamic/static, flat/round etc. Now, if we were to seriously DISCUSS!!! Bio characters, they are, generally speaking, flat and static within the context of a given story. There are exceptions, but they are fairly rare, and even then I hesitate to call any of Bio characters to be actually genuinely round.
SUBTEXT is something that has very fucking little to do with either previous bit, it's something that the author puts in on their own via allusions, or a reader derives on their own, a-la "Shakespeare was gay because he doesn't specifically mention a gender in one of his love sonnets". Bio has essentially zero subtext in their, hm, works, although I keep on hearing that rabid fans on BSN keep on finding something.
PRESENTATION is something I lumped together actually, it's more about stylistics & text quality really, if we want to be correct. Basically that's the author's style, whether he writes sentences well and then strings them well together or not; where his/her ability to write sentences deviates from the norm, etc. This has fuck-all to do with the plot, and a
lot to do with whether a story is good.
Also, yes, Bio's writing can be discussed via literary analysis, as dialogues and cutscenes are made up of scripts, and scripts fall nicely to the "literature" territory.
