For games like these, usually a way to grant an infinite or even an increased amount of time to dialogue choices. While some might like an option for the QTE sequence to succeed automatically, with exception of those that involve making time pressured decisions (shoot something or not). For me, these 2 options would be more than enough. Still the instant qte success would be more important. Especially for those who wish to enjoy the story more. The dialogue choices can be navugated with a guide, and a manually copied save in case of mistakes.
Like Freeze game or something?
