Metroid Prime: Federation Force recently launched on Nintendo 3DS, and Dragon Quest VII: Fragments of the Forgotten Past will be joining it on September 16th. If you're interested in one or both of these games, you may be able to try them out for free before shelling out your hard-earned cash. GameStop will be hosting a special demo event for both games at select stores across the country. The demos will be available from 1:00 PM to 4:00 PM (local time) on Saturday, August 27th.
