Beyond that, each Pokemon has lore. If you remember even one piece of lore around a Pokemon, like Magcargo having an insanely high body heat, you're more likely to remember that creature. Oh, and looks like there's a thing called a PokeDex that tells every player stuff like this whenever they catch a new Pokemon, making them each more memorable.
Much different than remembering which number from 0 to 9 is arbitrarily the 464th number of pi.
