It makes sense to make a character unlockable if they are a hard character to use. Characters that require finesse to play effectively seem like the perfect down-the-road unlockables, since they become available at about the time that the player attains the necessary skill to use them well.
I think unlockables are great, they do make me feel like I've accomplished something. Yet they can be counterproductive if the "overjustification effect" kicks in, a principle of psychology in which someone no longer participates in an activity for the happy joy feelings they get, instead it becomes more of a job. and they become consumed by the unlockables...
So, yeah. As long as that thing doesn't happen.
