Oh, I don't think Pokémon is too nerdy for MIT. I imagine it's quite popular, actually. I'm a huge Pokémon fan too! In fact, I even watch the anime in Japanese XD I know it's a terrible show, but I've learned a surprising amount of Japanese from it.
We should totally battle someday! I'm horrible at competitive battling, though. I don't know anything about competitive battling for Gen V, those stupid (but awesome) dream world abilities mean I have to relearn all the strategies. And I'm frustrated because I've been obsessing over college apps, so I haven't been able to play B2W2 XD
You know, I actually thought about writing my essay about Pokémon, but I decided not to. This was not because I thought the college would reject me for the topic, it was just that I came up with a much better one.
Go for it, just try not to sound too competitive or obsessed (definitely not sound as obsessed as I did in this post! XD). Good luck!
