LOL
That's all I have to say. LOL. Why?
1. You say you've been buying/playing the series since RBY. You play Yellow, you like it. You get Silver. It's kinda more of the same, but you like it. You get Ruby/Sapphire/Emerald. It's still more of the same; you start getting tired of the series... but you buy LeafGreen/FireRed. You don't like it. Why the heck did you buy Diamond and Pearl? It's obvious you grew tired of the series. It's your fault you bought a game you don't like, not Nintendo's for not changing the franchise to suit your tastes.
If you dare using the "I wanted to try it to see what's new" argument, think again: you could have waited and read some reviews before buying. They are usually quite accurate and fair.
2. Why should I boicot a game I love? Sure, you may have dispised it, but I love it. Should I follow your commandments or my own, personal view? I wonder... Next time you decide to whine about something you don't like, try not to sound so... childishly blind. You don't have the only word on the matter.
3. Phoenix Wright, Final Fantasy, Dragon Quest, Devil May Cry, GTA, MegaMan, Pro Evolution Soccer, Halo, Madden, the WWE brand, Mario, Zelda... let's boicot them all!
Sure, Nintendo/GameFreaks have been milking the franchise for so many years now... And, obviously, the next game needs some major changes to keep themselves fresh. But, come on... OK all go boycotting Pokemon RPG games!!! ? You sound so mature. Whatever.
