I can understand people may not like GnR, but some of the reasons they provide are really weak.
They play one specific machine and make blanket statements about every GnR having weak flippers or 90% right ramp rejects, left orbit is hard to hit, or skill shot sucks so game sucks (same skill shot didn't hurt the love for TZ.)
The multiball complaint is more legit, but it's really because they believe multiball must only be a special achievement because that's all they've known. Fair enough.
But only when one can understand the 2 ball modes are not an achievement to score jackpots in a traditional sense, the game opens up and a player can see the game differently.
It's a step to build song value for what is the real multiball toward the the risk/ reward element.
Again, not a game for everyone, but it's still a brilliant game. (Btw, so is TSPP, but apparently some people don't appreciate that game either.)
