I have a philosophical question

So basically knock-off pvz

not, it doesn't need to end in violence.

You could write a challenge about some chess master and his rival.
What I mean by violence is usually the rival or nemesis or villain, usually needs to be defeated completelly, or he repents or he gets destroyed.

There's also villains stories, but those are more of the tragic kind about his defeat.

In any case, drama is about overcoming some rival/villain that will be destroyed in some sense.
Being destroyed doesn't mean physical violence.

I agree, that's why is very hard to come with pure non violent ideas beyond puzzles.
However I was always interested in non direct ways of conflict.

At this point, you're talking more about writing stories in general rather than games.
There's some truth in what you say, but it's regarding to stories as a whole. Games can stand alone without any story at all, or just an afterthought.

I say is more a philosophical issue of drama.

You need some oposing force, in games this usually comes as hordes of enemies where the drama is get kill or not get killed.

Undertale sort of made fun of this by having a pacifist mode.

But you need some kind of oposing force that will limit your advance, otherwise you end up with a static conflict where nothing happens.

Maybe I could put nature as my big enemy and mix it up with some puzzle mechanic as my major obstacle.
That could be interesting.

>You need some oposing force, in games this usually comes as hordes of enemies where the drama is get kill or not get killed.
That is not necessarily true. I already provided 3 examples of games that don't have any of this drama above (solitaire, minesweeper, tetris). In general the genre of puzzle games usually comes without any story or drama at all, and they are by far the most popular and known genre throughout all age groups.

You can frame a puzzle as violence, but it isn't inherently violent.

a puzzle is abstract and lacks a story.

I would put puzzles antagonistic forces in the Man vs nature camp in some sense.
But this is debatable.

Tetris can be an allegory of communism if you want to do stupid interpretations.
