Firsts in IF
Inspired by , this page lists some important firsts in the history of Interactive Fiction, be it parser-based or choice-based, along with sources when available.
Note: all of these "firsts" are merely the potentially earliest games that exhibited this feature; there might be mistakes, oversights, or maybe we just haven't unearthed an earlier game. For instance, Adventure was long held to be the first (parser-based) adventure game, until Wander was rediscovered in 2015.
