But then why someone who wants to use their head instead of tugging at their dick would choose to play a porn game, as opposed to something with actual puzzles as main part of the gameplay? It's like making a first-person shooter specifically for people who want to practice their car racing skills.
You have given your answer when you call BBAS a game. And yes, BBAS is a game.
In general
Visual Novels: In visual novels, users use their choices to decide which direction the story will go. And determining a more desirable ending is the main goal.
Movies: A movie is a visual story. The goal of the viewer is to follow the story in a certain time from the beginning to the end.
But the games:
In the game, in response to the intellectual or physical effort of the players, a reward or achievement will be received. And the main goal is reward for effort.
The theme and story of the games have no direct relation with the genre of that category.
You can even have a shooter or racing game with a romantic or porn theme and story.
For example, the reward for effort in a game can be information, a photo, Gem , clothes, upgrade equipment or etc. while the said effort can be fast reaction, solving puzzles, solving riddles, aiming skills, and anything else.
If a person wants to have porn without any effort, movies are the best choice
If wants to be involved in the story, the best option will be a visual novel.
But if enjoys rewards for effort, then games are a good option .
In many cases, what is more enjoyable for the player than the reward is the process of doing the effort for the reward, not the reward itself (such as solving a puzzle or riddles).
The only point here is to choose the right category, which category is closer to what we want (movies, visual novels or games) and if we choose the game, which genre do we like the most among the available ones.
BBAS is a game in the genre and category of detective-mystery-riddles-puzzles games with a porn story theme.
Certainly, the difficulty of none of any games is at the level of each other.
Now , We have chosen a game in the category of detective-mystery-riddles-puzzles games and we complain about the existence of puzzles and riddles in it!
Or why should we make efforts?!
Does it make any sense?
