You must not read too many books. At least ones that don't use modern speech, but even ones that do, authors, especially novelists are known to stretch out their own vocabularies so the adjectives they use to describe situations and emotions don't become hackneyed and stale.

I know most of your posts have been troll-ish, but this one actually has some merit. Not that the speech used is difficult to comprehend, but I can definitely acknowledge that the game does use fancy words that are far from being common. It does help with the immersion, but I will also say that people who do a lot of reading and writing used to carry around dictionaries as part of their book luggage for the exact reason you pointed out. They are now apps on our phones, so no need to add extra pounds were it is not necessary xD.

I bet your brain blew up when Neo talks to the Architect in the Matrix lol
