Sword Art Online, DRAMAtical Murder Recommendations
Both involve some kind of a game world, though logging on to the game differs a bit:
In Sword Art Online, a more realistic way using "Nerve Gear" whereas in DRAMAtical Murder, it's more of a fantasy way like while standing in the street or just about anywhere.
Both have hot guys:
SAO -> Kirito
DMMd -> Aoba
Both are for fans of the game genre.
These two shows are very identical;
they both take place in games, interesting characters, and more. Both have very interesting plots, filled with action, comedy here and there, mystery, and more. If you enjoyed Sword Art Online, you most likely would enjoy DRAMAtical Murder as well.
DRAMAtical Murder would be one of my favorites, I highly recommend it.
