I don't find there to be much "luck" in WoZ OR Tron. Half the reason Tron is so popular, IMO, is because they did a 'storyline' type game like LOTR or Spider-man or TSPP, only they didn't make the requirements to complete it totally off the wall. It's very reasonable in terms of requirements to get to SOS especially, and even Portal is a fairly low bar. The 'difficulty' comes from game setup, really. WoZ....the 'lucky' parts of WoZ are did the stupid ball roll over all of the TOTO letters? Is the tilt loose enough to keep it in the State Fair balloon targets? I do agree that WoZ needs to be much more calculated because you can absolutely stack things that will hinder progress instead of helping it. That's not really the case with Tron, in which everything you can stack is typically wanted and just bonus points. It just gives you more and more to shoot for, and really the only two "roadblocks" in Tron are Zuse (Gotta learn how to shoot the 'E' from the left and hope your game isn't set up in such a way that leads to the right outlane.....it SHOULDN'T...) and the 3-way combo. Gem varies wildly from game to game..most of the ones I've played it's either makeable directly from Quorra, or ricochet off the TRON standups or drops. It's nearly impossible from right orbit on the fly. Honestly, unless you're going for the 25/50 million bonus for direct to portal, I recommend ignoring Gem until last, and if you can't complete it before the timer runs, just make the single shot in SOS instead of the FOUR before it, if it's a hard shot. Or go for right orbit light the arcade and take it as the mystery award. Lots of ways to make life easier in Tron....not so much in WoZ.
