I think P6 is a vast improvement over P4 in the sense that it has a much better toolset. It makes it possible for a mediocre craftsman like myself to make much, much better images with it (and ultimately that's what this game is all about). I would never go back to P4 and if I didn't have P6 yet I would get it without delay. But that's not to say that it doesn't irritate me to death at times. Like when half the dials overshoot and the others (in the material room) all work fine. I never tried P5 so I don't know how many fresh 'quirks' appeared there and got passed on to P6, and how many are fresh in 6. There are certainly improvements, like CL/E-F have discovered that mice actually have scrollwheels now-a-days and (would you believe?) a second button!! You get to right-click sometimes, it's quite a thrill! ;o) My pet hate (dating back to P3) is the absence of a select tool. It kills me that the default pointer is the move/translate tool which can mess up a scene so easily if you're not super-vigilant. So instead of selecting something right there in front of you in the scene you have to scroll miles down a list to get it. And, while I'm moaning, the other thing that riles me (also from P3 days) is the stupid camera controls. Everything in Poser is made more difficult by the fact that you can't easily get a camera pointed at (and zooming directly at, and orbiting around) a selection. If just ONE of the fancy additional cameras could do that I'd be a happy dolly-dresser. When Poser was young the only detailed things you could fiddle with were hands and faces, and so they got dedicated cameras, but we've moved along since then. Taking a close look at a shoe is absurdly difficult. There, I feel better now ;o)
