Saw some concerns regarding the controls and the impressions at TGS are not favorable.
http://forum.gaming-age.com/showthread.php?t=63339That's a link to a thread on Gaming-Age where people who have played it at the TGS show call it an "unplayable piece of poop."
Copied from the topic:
"Katamari PSP uses the D-pad as the left "stick" and the face buttons as the right "stick."
Up + Triangle = forward. Left + Square = left. Down + X = reverse. Right + Circle = right.
Up + X = rotate clockwise. Down + Triangle = rotate counterclockwise. etc. etc.
On the PS2 using two analog sticks is lots of fun because you can smoothly roll, turn, bank, pick up lines of things, etc. fun fun!
With two 4-directional digital pads, you can move fwd or back, move exactly to the side, or turn in place. YOU CAN'T SLOWLY BANK WHILE MOVING FORWARD. This makes it IMPOSSIBLE to pick up lines of objects gracefully, and makes the entire game feel like that sequence in Austin Powers where he's trying to parallel park the car as a series of 117 distinct movements."
I don't own a PSP, and I'm not bashing it, I just find it disappointed. This could be a huge, awesome game to own for the PSP. Let's hope they include a single-stick control scheme, as suggested by one of the forum posters, to make it control well.
