completionist ( kuhm - plee - shuh - nist ) ( noun )
(in a video game) a player who attempts to complete every challenge and earn every achievement:
"I’m not really a completionist, so I skipped the side missions and focused on the main story quests."

The specific guidelines for each completionist differentiates depending on the particular individual;
however, mine are listed in no distinct order below:

- Game is played from start to finish exclusively in vanilla mode (meaning no mods, add-on, cheats)
- No skipping any dialogue or cutscenes on the first playthrough (until it gets repetitive on NG plus)
- First playthrough is always played fully blind with no guides (guide is only used later for missables)
- Most complete, expensive edition of the game is always bought (all DLCs, trading cards, foil cards)
- Absolutely no cheating, exploiting, and shortcuts (this voids the entire purpose of an achievement)

I have spent 2,548.8 hours being a completionist.
