Played for 4 hours with the PlayStation Move and I'm not impressed.
The most annoying thing is the "aim assist". When cursor overlaps enemy, cursor sensitivity drops severely resulting in a sluggish feeling. When you crouch, cursor sensitivity goes down as well, messing with your muscle memory.
Every time you go from crouch to standing or from scope to hip view mode, cursor spawns in the middle of the screen and then travels to where it's supposed to be (that is, where you are aiming).
Cursor doesn't match the upward recoil. You can see the gun tilting upwards, the bullets on the wall drawing a vertical line, but the cursor stays still at the bottom of that line.
Vibration messes up accuracy A LOT. You better turn it off.
Some odd button mapping. In order to equip the knife (which you do by pressing L1 on the DS3) you need to press UP on the d-pad (hence releasing the left stick). Funny thing is the big, fat main Move button is not used at all.
You are asked to calibrate every time you go into a game from the main menu.
