If I rely on that logic, Pokémon would "crash" more often than ACNL would. If that statement is true, then the size has something to do with that.
Then again, I never had these issues on my current 3DS systems.
By the way, I'm kinda warming up to get Pokémon Y, given that the last Pokémon games I ever played were Red & Yellow (Game Boy) and Colosseum (GameCube). And if I do, it'll be probably on next year.
EDIT: Also saw that your new blog has been 404'ed.
