I played VV2 on the PC, and on the iPad/iPod I played VV2, VV3, and VF.

Only ONE of the collectible sets ever completed on the ap versions; that's one for each game. I played VF four times - each time for about four months - and only completed the coins once, and once in VV2 I got a complete set. But that was it.

When I played VV2 on the PC I completed three of them before I quit playing.

Those odds aren't too great...so are the ipad/ipod versions set to never complete?

Or is it just me? :P
