Played a couple different LEs last night, some quick impressions.
Sounds are much less wozzy in person. I don't know why the video came across that way, but I wasn't really bothered in person. I wouldn't say I loved the music & sounds, but they didn't really stand out to me, for better or worse. Maybe I'm just accustomed to what a JJP sounds like at this point.
Flippers are MUCH improved. Easily shoots better than any JJP ever, hands down. I am one of the biggest longtime critics of their game feel, which I generally detest, but credit where it's due, they changed something, and it seems to have worked. There are a couple long ramp shots up the middle, nailed them consistently no problem, with strength to spare. If there's any fade I didn't play long enough to notice it.
Slingshots are better than TS4, which if I heard correctly actually had weaker coils than standard. These feel back to normal I suppose, no weak ping-pong effect but no hard Stern snap either. They're fine.
Gameplay is, I have say, overwhelming, borderline indecipherable. At first I can make sense of things when nothing is running, but it's pretty easy to start a couple of the multiballs, and when you get into one, hoo boy. Everything seemingly stacks with everything. All the games I played had at least one three-MB stack, and once I'm pretty sure I stacked a 4th, but who could tell. Each with its own rainbow seizure of LEDs going, plus whatever mode(s) you start without even trying.
Best comparison I can think of is, I'm not a good POTC player, but once or twice I've had like 4 or 5 of the movie mutliballs running, where the whole game just goes nuts. GF is like that, except waaay easier to start. I was getting the megastack every game. Folks who like that will love this. It's just too much for me.
I think I'd really enjoy the gameplay as described in the featurette, but I feel like most of the rewarding stuff or complex strategy will be obscured by the megastack, with no real feeling of accomplishment. I guess owners who study and play it a bunch will eventually gain comprehension of the rainbow multiball blur.
