A hilarious detail in the game Estique is how its English manual is deliberately poorly "translated", and in the game itself, cut scenes are slightly censored in the English version just like Nintendo used to do it in the 1980s.
The game Tunic is a wonderful homage to the original Zelda and NES games (and a great game unto itself). Part of it is that you discover aspects of the gameplay through piecing together an in-game NES-style manual and deciphering the scribbled notes on it.
