I feel so disconnected whenever I read a manga with game-centered world building. Like, stats? Ability gifting? I mean, jobs are one thing, but "ability gifting"; I've never heard of it. Does it have to do with Final Fantasy? The only MMORPG game I've played is Adventure Quest World (as well as Dragon Fable and that Mech one). Guilds? Are they really effective for society? Ehhh...
