Just as "special" as your son in Fallout, right? Because that was a terrific idea.
We do not need a rich main storyline. Add in some side quests, or make the normal interactions more unique - for example, maybe spend some time making more than 1 or 2 speech lines for every bandit and lord in the game. Add somre interesting lore, that different lords actually have personality and might have unique quests. We do not need a hand-holding arc that dictates to us what we should do.
I already feel like parts of the quest pidgeon my character into a specific "hero type" that I am not even interested in.
Lets be serious, the main storyline will probably be modded out anyway, since the modding community, less than a week in, is already fixing all the other blunders, horrific oversights, and honestly stupid decisions made by TW out the gate.
I almost feel like TW should have just released a barebones fighting engine and just let modders do the rest.
