Romance, a wonderful and tricky things in games. In Dragon Age Inquisition I had felt extraordinarily limited. Really only having one choice. In Skyrim you can marry and have children which do their own "limited" things which I think is better, but like in Fable all the people seem to lack personality. I understand that it can be difficult to justify time to devote developing stories of potential non-companion characters. In Divinity II the blind magister would have been a prime candidate for me his tears and inner turmoil made him all too appealing. Back to the point though time is money and if you were to hire 1000 writers it would still require a lot of work to check for continuity and edit and simply put writing for a game is very very hard work and the more writing you have the more difficult that work becomes.
Out of the characters we've seen so far I'm most tempted by the wizard. His "explosive" back story is intriguing.
