What is your impression from playing 8 way games? q-bert?
Eh, it's weird. First off, the action on the Sanwa JLF's is so light, that it doesn't feel like an arcade stick to me anyway (at least not from my day).
The 8-way gate makes it feel even less like an arcade stick, but it does make you extremely conscious of exactly where the stick is.
When I do a quarter roll in a fighting game, I know that I'm doing it properly because I can feel it it go into the right notch, slide easy to the diagonal, then I can feel resistance when it hits the diagonal point and changed direction.
It feels like training wheels...but I need me some training wheels.

Some day I'd like to have enough control where I can move the joystick just far enough to do the moves without having it pushed up against it's limits. Then I could take the training wheels off. Not sure I'll ever get there.
I hadn't played Qbert with it until this evening. I did a LOT better than usual.
I did move the joystick up and down instead of on the diagonals a few times,
but for the times I was in the right general direction, the gate guided me in.
On a side note, a while back I hooked up a Sanwa JLW with the restrictor set to 4-way.
I wanted to see if it was worthwhile to add a separate 4-way to my control panel.
It really didn't do anything for me. I didn't do any better at the games and it didn't feel any more authentic to me.
I think I'd need an old Wico for it to feel authentic to me.
Everyone has their own tastes though. Your results may vary.
