I remember back in the days when it was only pokemon with red+blue games out, at the time I was able to identify all 151 pokemon at the time but eventually it got old and I forgot about them.
In the end it just dragged out, with all the expansions like ruby, diamond, gold and what not, and magically more pokemon just so happened to be discovered :/
lol whenever I think of the new pokemon series I just think of 'giraffamon' because I recall a pokemon that just just a giraffe, talk about losing ideas for pokemon, just throw in an animal and ad -mon on the end and your done.
edit: I remember the red/blue game had the glitch to get that glitched pokemon or was it to see mew at the very end hall of fame (whatever it was) lol I did it and true to its rumours, it actually did mess up your game....
