This is a screenshot from Somari. The screenshot copyright is believed to belong to the distributor of the game or the publisher of the video game or the developers of the video game.

The entire screenshot: because the image is taken from the game, the entire image is needed to identify the product, properly convey the meaning and branding intended, and avoid tarnishing or misrepresenting the image.

The copy is of sufficient resolution for commentary and identification but lower resolution than the original screenshot. Copies made from it will be of inferior quality, unsuitable as artwork on pirate versions or other uses that would compete with the commercial purpose of the original artwork.

Main infobox. The image is used for identification in the context of critical commentary of the work for which it serves as screenshot. It makes a significant contribution to the user's understanding of the article, which could not practically be conveyed by words alone. The image is placed in the infobox at the top of the article discussing the work, to show a primary visual image associated with the work, and to help the user quickly identify the work and know they have found what they are looking for. Use for this purpose does not compete with the purposes of the original artwork, namely the creator providing graphic design services to relevant concerns and video game marketing to the public. 

As a screenshot, the image is not replaceable by free content; any other image that shows the packaging of the item in question would also be copyrighted, and any version that is not true to the original would be inadequate for identification or commentary. 

Use of the screenshot in the article complies with Wikipedia non-free content policy and fair use under United States copyright law as described above.
