I'm new to Tron, but I REALLY like it. I modded mine to with an inch of its life. Eli Ramps, Cointaker LEDs, LED Flipper buttons, Latest Arcade Mod, Pinblades, all the usuals.
I absolutely LOVE SOS. It's such a great high pressure opportunity to lead to the big show. Total blast.
When I started playing, I'd focus on LC MB, and Disc MB, and try to pick up Quorra in the process. I'd end up at SOS with at least 3-4 inserts lit solid, and then SOS seemed like an insurmountable task (and likely IS).
Now I focus strictly on the Gem shot. I advance Quorra in the process, start and complete Gem, and really focus on getting inserts lit solid BEFORE starting SOS.
The last few times I made it to SOS, I needed only one insert. That seems a lot easier to handle.
I made it to Portal Friday night. I've only had the game since the start of the summer, and I've been away for much of it. I would estimate I have fewer than 200 plays on the machine.
I'm not trying to blow my own horn here. I'm trying to say that a methodical approach, with a focus on the Gem shot will take you a long way in this game.
I didn't even scratch the surface in Portal. I had a fun Multiball while trying to take in the sounds, and the new DMD scenes. Didn't make it far, or rack up a huge score. But getting to Portal felt amazing. My score was just over 88 Mil.
I'm a total Tron convert. Fast, fun, and challenging enough to drop a few sub 10 Mil games on you, yet deep enough to be incredibly rewarding when you're in the zone.
