Ey, it's nawt my fault :|
Firstly, my post was a personal opinion in response to the opening post (which contains the results from a lengthy, albeit flawed survey). For most of them, I carefully picked one Pokemon based on how much popularity I felt it had based on (1) competitive battling scene, (2) features in artwork / graphics / other media, (3) number of "appreciation" threads / clubs, (4) rarity / in-game or anime appearances. Lileep was really the only one I had zero basis for, other than it was either Anorith or Lileep. And fyi, I find Cradily sooo adorable. @@
But yeah, the only real way to compile the list of most forgotten Pokemon is to have a thousand Pokemon fans list all the Pokemon and assign "forgettable" points depending on how long it took the fan to name that Pokemon (the closest to last, the higher the points) and then compile a list. The flaw with the PT game is that every player shares a list and therefore, even if only one person remembers a certain Pokemon, then that Pokemon can't be considered "forgotten." In addition, both methods share the flaw that Pokemon may be listed just because of association. For example, if Shroomish isn't popular, but Breloom is, then Shroomish can't be considered forgotten since most people think of Shroomish when they think of Breloom. Then there are antics involving similarly colored Pokemon, how the Pokemon evolves, the name of the Pokemon, and just plain human association.
