I am not disagreeing on that, it's just the timing of both scenes.
Wouldn't news of MC's ex-wife dying have more impact if you already had seen the flashback sex scene (and know what she looks like before hearing of her demise)?
You right it would have been much better from every standpoint if this was the defacto opening to the game as a dream sequence as well. Seeing as the MC apparently wanted to get back with his ex as stated by his inner monologue. Time passes feelings change. If you don't trust your readers enough to know this then why are you making an adult novel and not a children's one?Maybe, that depends on the way the dev wants it presented. The way its written we get the first impression that the ex was a terrible person from the protagonists point of view but the flashback contradicts that and the more we learn reveals what really happened and why the protagonist first reaction was the way it was.
Showing it earlier wouldn't have given the flashback the same context.
