Oh, @VinMcCarthy. Yes, Mew is a great pokemon, by all means, a naked mole-rat of a pocket monster is surely the best! Wrong!
Piplup is the all-time best pokemans.
And here's why. In Diamond and Pearl you can get this stupid guy as a starter, right? But if you never evolve him. If you let him stay dumb, cute, and beautiful, he'll be stronger than ever before? Oh, why do I know that? asks @VinMcCarthy. Well, it's because I used to work at a GameStop, that's why.
But to be serious for a second, I had a falling out with the Pokemon games for a while and when Diamond and Pearl came out (while I was working at a GameStop, that part was true) I found myself falling back in love with the game. It was almost like I was experiencing the whole series for the first time. It was great. I lost hours and hours playing that game and if I could find my Nintendo DS, I'm pretty sure I'd be playing it right now. So, maybe I like him for more sentimental reasons instead of scientific.
[note: Piplup is scientifically better than Mew]
Thanks @VinMcCarthy for another great video game challenge, I can't wait for the next one.
