Is this suitable for wrapping a standard game box?

Yes. It is a general-purpose gift wrap, so it handles a game case or a small boxed gift. Larger items may need two sheets.

Does the glossy finish make tape stick?

Glossy paper generally holds tape well, but press it down firmly. Matte tape blends in less than on matte paper.

The design uses Pikmin and Captain Olimar imagery, but the listing does not state an official Nintendo license. Treat it as fan-themed wrap.

Yes. It works for wrapping party favors and small prizes, and the motif fits a Pikmin-themed table.

It costs more than plain wrap for the themed artwork. The paper itself is standard gift-wrap stock, not premium heavy paper.
