Words have different meanings when applied to different context.

If this was 2001 (when we were playing Halo 1) and we were talking about a 1993 game (original Doom), this wouldn't even be a discussion. But games evolved fast during that time.
What this shows, if anything, is how little games have progressed in just under a decade.
From that point of view, TLOU is hardly retro.
