Ya know, I have VF and VV 1 & 2 on my iPhone - and I'm just itching to see VV 3 show up at the App Store for my iPhone!!! Is it worth it to have these games on both systems? Like, are they actually different in that the iPhone app is simpler? If so, it will help me decide to buy the PC version of VV 3 and not feel buyer's remorse if it comes out for the iPhone. Cheers!
