I guess I am emphasizing "from Paradox" because for me they produce games that don't fit predictable molds and make interesting gameplay out of surprising subjects (if anyone told me that I would sink 200+ hours into a royal marriage simulator then years ago, I'd be a bit surprised, but Crusader Kings II is amazing, and still a royal marriage simulator)
Obsidian is a great company that disappointed me with their last effort at a BGII: pillars had a lot of potential and did very little with it, we'd meet a cool companion, e.g. Kana, follow them on their quest, and when it arrived it was a meager fight and an uneventful conversation where Kana is like, "oops guess what I thought was going to be awesome is actually pretty lame". All I felt was, well Kana is right, that was really lame. This is why, at least for me, "New rpg from Paradox (also Obsidian is making it)" sounds more promising than "Obsidian is giving us more Pillars type goodness!"
And yeah, being able to play a baddie is very promising, because I cannot remember a well-done evil narrative since Arcanum: KOTOR was stupid evil (e.g. I got turned off dark side in KOTOR 2 when the dilemma is: a bunch of evil mafiosi are screwing migrants, Light side is help the migrants through peaceful negotiation, I wanted a Dark Side solution that enabled me to feed the mafiosi their own entrails, instead I was encouraged to screw the migrants extra hard, for absolutely no benefit to me and no sense of a resolution. Evil for evil's sake is pretty stupid when you don't get to indulge yourself), Baldur's gate was neutral evil at best, but Arcanum really had a nice sweet spot in letting you do terrible things for fun and profit.
I hope tyranny carries on that mission with aplomb.
