Well darscot sent me a PM, as I was in the process of replying he deleted it.
So I'll post my response here.
"It makes not a jot of difference that you are a software engineer - what it does tell me is that you aren't working in marketing.
I don't understand what you mean by games hanging on the wall - I just have trophies - all my games are set up for playing.
The main difference between Fifa (and any video game) is that EVERY iteration of the game in every different living room around the world is the same or at the very least can be set the same, making comparisons between scores true and meaningful.
2 pinball machines set up next to each other play differently based on any number of things, steepness, left to right tilt, tilt settings, outlane settings, difficulty settings, etc. These are all things that the user themselves can control and alter EXACTLY- then you've got things the user can control to a certain degree, switch gaps, polish, choice of rubbers, etc. THEN take into account things that can't be changes by the user, thickness of clearcoat, natural warps in playfield, dimples, wear, minute differences in positioning of ramps or posts and you'll soon see that no 2 machines ever play the same - as such comparing scores between just 2 machines is futile, let alone trying to set up a highscore table across all games.
Pinball Arcade has these goals and a universal highscore table - that does work - BUT at the end of the day it is a video game of a pinball machine - not an actual mechanical pinball machine with all it's nuances and randomness - the very reasons why many people prefer pinball over video games.
Dutch Pinball, when they released Bride of Pinbot 2.0, did exactly that. Set up highscore tables, achievements, trophies, which are all uploaded onto their site - it didn't attract masses of additional sales and didn't work out - there's existing proof that it doesn't work.
As for crazylevi - I disagree with a lot of what he says, and often the manner he says it, but in this instance I agree with him 100%.
