Hey, PresumptivePanda
As of this moment, what I have for the villain is his character pillars: overgrown ambition, paranoia, self-aggrandizement and genius. I also have a slight backstory and a monologue that explains his motivations and what drives him to do what he does. The goal would be to have a motivation that you can’t simply argue with or find faults in it. This kind of villain motivation would probably be the goal for every aspiring writer, therefore a rookie mistake, but that’s still what I’m aiming for.
At the moment, I haven’t the slightest idea how he is going to look like except that he will be a human and a male. I’m hoping once I get his personality fully fleshed out, I can base his appearance on his traits. And since I only have a half-vague/half-concrete vision of his personality, I can’t do that right now.
There is one other aspect to consider: I also am not sure if there will be a boss fight or not. If there won’t be a boss fight, the quality of the dialogue has to really increase in order to compensate for the lack of gameplay.
You may be asking “OK, why not have both great dialogue AND boss fight?” Well, I wouldn’t say no to that, since that is also my goal. If the boss fight doesn’t work out, I’ll really have to give 120% to the dialogue, content-wise or at the very least voice-acting wise.
