The Metroid franchise is one of the darkest in Nintendos repertoire, and the series has already shown that it can transfer its signature moody atmosphere to the small screen through both Metroid II and Metroid Fusion. Prime Pinball is hardly one of the series' leading lights, but its simple gameplay and point-scoring missions give it a pick-up-and-play appeal that you don't get with the core entries in the franchise. While the original title made use of the DS's twin screens, MPP would actually be a better fit on smartphones as the display more accurate the mimics the dimensions of an actual pinball machine. If mobile gamers are looking for replayability, this offers it in abundance, as there's always chance of beating your current high score. Whether its a fully-fledged space adventure or a more casual spin-off, theres surely some room for Ms. Aran on the smartphone scene.
