Will buying the Expansion also include the game?

Tell him to get the game now and start playing to set himself up a little . As it stands Dark Knight would need something levelled to access it even beforehand.

Sounds like Dark Knight is what Death Knight is in WoW.

Sounds like Dark Knight is what Death Knight is in WoW.

While my knowledge of WoW lore is shaky at best (haven't played anything Warcraft-related since Warcraft III), this comparison is weak at best.

The core theme of Dark Knight in Final Fantasy lore is a warrior that harms himself in order to harm his enemies more (Souleater). They typically also use at least some black magic.

WoW's Death Knights are former evil minions on the path to redemption who use powers of undeath.

Only one Dark Knight in FF lore is a former evil minion on the path to redemption (Cecil from FFIV), and no Dark Knight has ever used powers of undeath. Given that all we players are established heroes long before we get the chance to unlock Dark Knight, there will be no "evil minion" background for us.

If you're arguing that Dark Knight is similar to Death Knight in that it's a hyped up job to draw new players into the expansion, there's some truth in that - though anyone who's a Final Fantasy fan was pretty much expecting Dark Knight to show up in some form sooner or later.

Stuff

Leon was actually an evil Dark Knight before he joins as your final party member (FF2). I don't know of any Dark Knights that use the black magic ability, if you're saying they use abilities that would normally otherwise be black magic then that makes sense, other than that I haven't played FF11 so if they use black magic there then okay. Dark Knights use the power of darkness to fight which the first ability to that was Souleater, though it's worth bringing up that the magic knight from FF3 was rewritten into Dark Knight for the 3ds remake, and used dark swords in order to combat multiplying enemies.
