there is only one kanji that means all of them , so semuanya lu musti kuasailah...
simplified chinese is just an extension of traditional chinese. which means you better learn traditional chinese and then put a plugin on to it (the simplified chinese).
Simplified seems easier to write because it has less stroke that traditional chinese, so handwriting seems faster, but it is not truly easier than Traditional because it takes more brainpower to store new radicals created for simplified chinese, because in simplified chinese, all the old radicals from traditional chinese still exists so as a result you have to double your brainpower to learn simplified chinese. At least that was a professor in Chinese Linguistics at NTU in Taipei had reasoned to me last time I came by his office to show him my work on the game to improve kanji retention.
