Well, Ixion Saga is based off of an actual MMO, whereas SAO is entirely fabricated, and the books the anime is based on are actually from much earlier on in the MMO world, like back when FFXI was still fresh and relatively new. That said, the SAO anime continues to drive me insane with its terrible pacing.
Sunday night was anime night. Jojo was hilarious, but looks like it's only going to last the now normal 12 episodes which is highly disappointing. Magi was amusing as well. Knowing the manga, I can see it becoming another long series similar to One Piece/Naruto/Bleach/Fairy Tail/etc.
I agree on the Jojo bit. As for Magi, I love everything about the anime, except for the fact that they can't pronounce the word "Magi" correctly. For those not watching or not sure what I mean, In the anime, they say "Maggie" when it's pronounced "Maji", which is entirely within Japanese phonology, they're just doinitrong
That said, the theme song is ******* awesome. Also, I'm enjoying Code:Breaker's anime too, even if Sakurakouji's voice is way to deep for her character. It makes sense in the early chapters' story, but once they get a bit further on, it's going to start to feel weird
