Trial and Error Based Gameplay

[Koh]

Exactly, that's why I said it was an extreme example, and any game that's like that, lol. A more humble example of trial and error would be Bram Stoker's Dracula's 8-bit games. Especially in Scene 3's Nighttime stage.

I only got through mostly unscathed because I've played it over and over and memorized where every enemy was placed. But many of them are placed in such a way that it's literally impossible to know they're there, until you've already committed to the jump and taken damage. This sort of trial and error was present in many games of old, like Ninja Gaiden.
