Quoted from woody24:

I wondered if that was going to happen. And I dreaded it. I don't care for Zen Pinball's physics and cartoony scoring system. I figured they'd screw it up, but after seeing the video's, it actually looks good.

Quoted from tamoore:

Should probably be zero, I'd think.

Quoted from woody24:

I just don't notice any difference in the ball physics. Shallow hits, ones that just go past the slings, still feel too heavy. That doesn't seem to have been changed one bit. But they did do something about the shots though. I was hitting the ramps more consistently.
And it could be a problem with the sound. Sort of a placebo effect. There's a "thud" sound made for every post or rubber you hit, and it's the same tone no matter how fast the ball is going.

Quoted from BenLogan:

Guys, if you’re interested in this remaining a proper pinball simulation, versus a pinball flavored video game (not that those aren’t fun too), I encourage you to download the beta on Steam and comment in their forum.
The most recent version (released yesterday) changed the ball physics more toward traditional Zen fantasy physics, even in their Arcade simulation (vs fantasy) mode. They’re a good group of devs who really seem to listen and respond to community feedback. Let’s let them know there are a bunch of us who want a proper sim!

Quoted from Raegor:

Why are you complaining about something you know you can disable?

Quoted from VALIS666:

You have to change the mode from... I'm forgetting but I'm sure someone will remember what they're specifically called, but the the default mode is with easier physics, table animations, and ball trails, while the Arcade(?) mode is with realistic physics and none of the things mentioned previously.
