Apps installing to SD

Has anyone been successful with this? I am only concerned for large games. Take Dungeon Hunter 2 for instance, it's near a gig. If I move the files to the SD card, it crashes at launch (likely some weird directory issue). So I have to leave large amounts of data on the internal storage. Can someone guide me or flat out tell me if this is something I will have to deal with or something I can do differently?

Thanks!

 

It actually doesn't appear I can move any app to SD like one normally could on an Android device....all I can do is literally move the directory with a file manager.
