Quoted from fattdirk:
It's only an issue on pinside. The average person never even notices the bugs. I would guess that the majority of pinsiders don't even notice incomplete code or bugs and only are notified of them by reading on here. A lot of collectors are just terrible at pinball. You don't have to be good to enjoy the game. I wish Stern cared about making complete games, sadly I think they only really care about the cash flow.
That's always been the conundrum about pinball and what it is. Is it just a 2 minute time killer in a bar, or is it a "real game"? I'd like to think it's a "real game", a game of skill...and games of skills have to have sound rules and logic - AKA, complete code & bug free. If Stern was content to just make time killers, why are they bothering with these deep (and confusing) games like GOT, GB & SW? In 2010, they went in a different direction. IM, Tron, Avatar, BBH, and TRS have very simple rules...practically cut 'n paste with a few tweaks. They wanted to "dumb things down" since location players had no idea what to do on deep games...and deep games had to have longer ball times. With IM they made something fast, fun, quick, addicting, easy to understand, hard to master. Collectors didn't like those games at first, Iron Man sold like crap - so they went back to more complex and deeper games to lure the home buyer...because the home buyer KNOWS a good game from a poor game, and expects a bit more depth and thoughtful gameplay than a location player. That's why games like TSPP & LOTR sold so well.
Fast forward, people ended up LOVING games like IM and it went back into production with the Vault Edition. Home buyers started to favor fast paced quick balltime games vs. LOTR type stuff (hence the Hobbit-hate). So, based on current tastes & customers, I have NO IDEA why they're still attempting deep games and not just doing IM/Tron type stuff. Like you said, average person doesn't notice...and they just don't have the schedules to make super deep & polished games. Maybe they need to go back to their 2010 design philosophy.
