Stppwii is a port of Simon Tatham's Portable Puzzle collection to the Wii. You will need a Wiimote and either a Classic Controller or USB keyboard to play.
On the series s/x you can use a external HD but any next gen games must be on your internal ssd, or you can buy a ssd expansion card, but pricey. Any xbone, 360, or og Xbox games can be played from external tho.
