With a popular anime based on it, Pokemon is one of nintendo's 4 biggest selling franchises, this is the sort of series everyone has owned at least one game of.
This really is a Love it or Hate it kind of series I like it because it is Fun, Interactive and nothing like the campy anime series.
The best games in the series where of course Pokemon Red, Blue and Yellow all though the new games are still fun there are just too many damn pokemon theres like 400 of these things that only say their own name!
