Pocket Gamer writes: "Whether it's coins, shot glasses, or digital creatures, the desire to collect things is inexplicably human. There's no functional purpose for amassing a huge collection of shot glasses, for example. It's not as though you're going to use all those tiny glasses in some grand binge (and if you do, then you have an entirely different problem).
Similarly, you're not likely to use all of the spectrobes you discover in your time with Beyond the Portals, yet the drive to catch them all is strong. Resist it - there's no need to get all worked up into a collector's frenzy. While these creatures provide loads of gameplay, only the most devoted of collectors will want to travel Beyond the Portals for them."
