its on nintendo 64. you are carted through courses in nature( power plant, volcano, cavern, beach, river, valley, space) and use the poke flute, pester balls, and apples to get better pictures by making the pokemon do poses unintentially. its really funny and i think its awesome. im playing it right now. look up pokemon snap on youtube. professor oak scores your pictures and you fill up an album. it may not sound exciting, but you actually have to sort of figure out what will get a pokemon to appear there or do that or evolve.
its really cool and the music is good too.
