This might be the best soccer game on the system when it comes out.
FIFA Soccer 12 will be the second soccer game on the 3DS when it comes out this fall. From my experiences with Pro Evolution Soccer 2011 3D and FIFA 12, I'd venture a guess it might be the premier soccer title on the system.
The best thing I can say about FIFA is that it feels very familiar to me as a casual FIFA fan. With little trouble, I was able to pick up the system and dive right in. The Circle Pad feels tight for controlling players, and everything else controls just as you'd expect in a basic game of FIFA. It's lacking some of the bells and whistles usually found on the second analog stick of other consoles, but it feels good.
Shooting can be done traditionally, but FIFA adds a touch screen shooting mechanic where a net will appear on the bottom screen, and you use your finger to touch and hold a spot on the net to shoot the ball. It can be a little tough to use the touch screen while looking at the top screen, but with a little practice, it becomes second nature. It does add a nice layer of precision to shooting as you can easily pinpoint an area of the net.
I also played the Street Soccer mode, which has a rounded pitch. The rounded globe-like nature enhances the 3D effect, though the view of the gameplay suffers because you're not looking from the sidelines like you are in the other mode.
FIFA 12 seems to be progressing nicely, and for soccer fans on 3DS, it should be a good experience this fall.
