Some popular video games that have a reputation for being very hard to finish are the "Dark Souls" series, the "Ninja Gaiden" series and "FTL." "Winnie the Pooh Home Run Derby" is an example of a children's game that gained notoriety for being too hard to finish.
The "Dark Souls" games are a mix of fantasy and role-playing that have become popular due to an unusually high challenge level. The "Ninja Gaiden" series also has a reputation for its difficulty, going all the way back to the roots of the series in the 1980s. "FTL" is a game that features randomized elements that usually stack the odds heavily against the player.
