Sometimes I really think no one knows what they're talking about when it comes to physics. I will be the first to admit I'm no expect, but it felt fine to me. You see people talking up the phyics of one game, then soon enough people saying it sucks. The visuals I'm not worried about, they'll be much, much better on other platforms as we've already seen, and most likely on iOS too, with updates.
There's no shortage of people who find the physics in Zen/FX series awful, and such people that feel they're pinball experts. Then you get people who say the same about The Pinball Arcade, but there's a consensus TPA's better than the physics in the Williams Collections from before (which people loved), but that's still not good enough for other people I suppose.
Then you get people who are more logical, and say those people just want heavier action, and are probably used to arcades where the tables are tilted more so the ball feels heavier, while Farsight is probably using near-mint tables on a more level "factory" setup. I'm pretty sure Farsight records footage of the tables being played and compares each tables timings and performance against what is in what they release, they do strive for perfection. today.
