Gede: Now, here is what I think to be the problem with games-based movies: the story and plot serve only the gameplay. It is gameplay that makes or breaks the game.
However, on movies (books, series) the story should serve the characters. You
can make a successful movie without good characters (action movies like The Fast and the Furious)
You forgot about one important nuance. Good action movies rely on spectacle and stunts. But the thing is, looking at stunts and spectacular moments can never be as exilirating and engaging as participation in stunts and making spectacle yourself. And that's why action movie based on a game could never match the game itself, where you feel like you are the character that performs all the tricks.
And thus, I agree with you, that game adaptation should focus on characters and the world lore, showing things that in the game wouldn't get much focus. And what proves it better than anything else is that there are very few good movies based on games, but there are many good
series based on games - Sonic the Hedgehog, Higurashi, Arcane, and other series that have enough time to show characters and other things in depth. Even not very good series, like Castlevania have bright moments, when they explore something that was mentioned in games but didn't get a spotlight (like Dracula's relationship with LIsa).
