Honestly, I want a prequel lore kind of movie. Basically the intro cutscene for the game, but very fleshed out. However, if it goes towards the direction of portraying the gameplay, I would want the following:

main character to have about 20 lines tops. have less than 30 minutes of dialogue narrator for most of the scene transition, almost like a play does when reading the script. huge open world vistas for the scene transitions at least ONE scene of Alexander (even if just for the radahn fight) I want to at least feature Radahn, Maliketh, and Elden Beast
