LoTR!
I feel like it's got a lot of problems. Barad Dur always sounds like somethings broken, Palantir... a standup target THERE? TZ had been around for a decade, and they went ahead and repeated that known-problem target placement, only they made the target 3x as large, so it gets whacked 3x as many times. Should have been a captive ball. The saucer that only registers weak shots is almost impossible to hit on games with well maintained flippers (so it works on location) - should have a back on it. The ring periodically blows fuses in normal operation, and often fails without any apparent reason, and the center ramp for the ring shot is near impossible to make with poorly maintained flippers. The playfield layout is generally uninspiring. I think it's carried almost entirely by aesthetics (it looks and sounds wonderful).
TOM i'm also not impressed with - it's not a bad machine, but I feel like it's B-list, not A-list.
Northvibe: RBION is not generally considered A-list, afaik. I'd put it as a strong B-list, fun table. Feels Lawlor-y, IMO, if you don't like the feel of TZ, you probably won't like RBION.
