When it comes to cartoon like Anime, Fairy Tail all the way! Huge fan, and I love the story lines and the characters are all so well developed! Erza has to be my favorite character! Or Full Metal Alchemist. Sure it's gory at times, but so good! When it comes to more traditional Anime, I have to go with Sword Art Online! Sure the story skips a lot and could have been so much more, but the idea behind it and how well it's developed makes it the best! Now here's a question for you all who have watched it, if you gotten SAO, but waited a day to play it, (because of work or something) and saw the news about it... Would you still log in? A new one that I have just started is Log Horizon. Take Dan Straight from Fairy Tail + Morgiana from Magi + SAO = Log Horizon. It's not bad, but entertaining. But that could just be from my Gaming perceptive.
The last one isn't exactly an "anime" but I think still worth mention would be Rooster's Teeth RWBY. The fight scenes are simply amazing and weapons are so creative!
