Alright OP, I'll play along. Ok, let's say walking and talking segments are now reffered to as 'walkie talkies.' What about item descriptions? What about the segments where there's exposition with neither? What about the exposition where you read it from a book?
You see what I'm getting at? There are so many ways to expose stuff, it would be downright impractical to start labelling everything. Discussion would be bogged down and you could only discuss this shit with only the autists at TVtropes, because they're the only ones who give a shit.
"Keep it simple, stupid." If the word "exposition" is good enough, why fix it?
Alright, I'll elaborate on why 'walkie talkie' is a bullshit term that should not be used, since you can't figure out why it sounds utterly ridiculous.
1) If these segments should be named, every other segment should be categorized as well, making things highly impractical.
2) The term sounds childish and is silly (like you said), unbefitting any medium that should be taken seriously.
I don't understand how you would see my post as "being offended." Irritated, sure, but far from offended. I was addressing the fact that you found the term 'walkie talkie' to be fitting because it is silly to be bullshit, and then you go off on a tangent saying I'm mad?
Alright, now we're getting somewhere. Let me ask you this; if you want video games to be taken seriously and these issues to be addressed (prolonged walking segments), why come up with childish, bullshit terms for a sub-category of exposition? Isn't the term 'walking simulator' enough? Like I said eralier, if you complicate things too much, it just confuses people. Imagine trying to talk to a person about your favorite video game, but every segment is now categorized into some bullshit term. It would sound something like this:
"Hey Mike, I really enjoyed TLOUs walkie talkie segments, but the run and shooty parts werent nearly as fun as the stab'n'rape sequences. I happened to dislike the findy-keepsies part as it was too un-schway."
If you want your discussions to be straight out of TVtropes, I guess I can't stop your autistic ass.
