"Boss Fight" Ideas

[Kein]

Boss fights will completely pull the player out of whatever immersion you have, so I'd advise against it. Also, the one from Abduction was only acceptable because it played Zelda fighting music.

Well, actually, such kind of "boss fight" are possible, even without ruining the immersion/atmosphere. For example, if you encounter some powerful enemy in the location (which is, of course, justified by the story), who haunts you in this location without giving you a rest, you could use the tools and aspects/features this location provide to kill/get rid of him. Like locking him somewhere, or pushing into the pit or luring into some kind of mechanism to crush later. I can see how it could be consistent within the gameplay. Conception is not a problem , the execution/realization is. It is hard, despite the fact it sounds so easy.
