With any level of proficiency in a particular aircraft there will be time based on your experience that starting the aircraft and running the checks are intuitive and easy. I think having the quick start feature represents that.
To a non pilot with no first hand experience in operating an airplane I can see the appeal and that feeling of immersing yourself in it. Your first few times of checking, verifying, doing and all the minutia might feel like immersion and interesting but once you get a handle on the keystrokes you'll develop mind and muscle memory which will take that immersion feeling away rather quickly before it becomes routine. You'll end up pushing the buttons as quick as you can because you want to actually get started and flying and wishing you had a quick start function.
When you sit a new crew down in a simulator during initial training in a jet they've never flown it can take an hour or more just to power the thing up and run through the checks from cold and dark to ready to fly. When you get on the line and you spend 6 minutes or less from closing the door to being ready for takeoff that hour seems silly. You'll develop a cadence, a flow and use the checklist as a done list and it really doesn't take long to accomplish everything you need to do. The same will happen with a gamer however with no real systems failures there isn't much reason to do all the checks since what you're checking is to make sure things are working...and they are.
