So with the game will it only be playable on the site or will you be creating a version that can also be played offline as well?
As a champion of light do you have a choice of not doing as the shadow says or is the game all about the fall of the hero?
Is the champion based on certain criteria of emotions or is it all based off your choices and how you decide to take things?
It'll be online at launch, but I definitely want to offer an offline version, I just have to figure out how to do it.
I'd say it is about the fall of the hero in that context, but how it effects the player is going to be down to them. If they choose to cling on to their past and try to do the right things in difficult situations, they are going to be more emotionally torn that the player who embraces the dark side, so to speak.
Tying into the last question, it is going to be mostly about how you decide to take things. You always want to give the player a choice, but those choices should shape them, so how you act will eventually begin to determine the choices available to you. To simplify and use a popular example, say, if you start at chaotic neutral and repeatedly make chaotic evil choices, you'll lock out the ones for chaotic good and get new chaotic evil ones. I'm going to write a long post about this soon-ish, but ideally, you want people to become invested in their choices, and by extension, their character.
