I'm playing Karlach and really enjoying it. Only downside is that the act 1 romance is limited by the whole "I will burn you with skin contact" thing.

Lae'zel's Origin has enough unique dialog going on to make it worth it's own run. I've had a lot of fun with it and it's a little better than a Gith Tav in some ways.

I’m playing Gale. It’s fun. Magic items nom nom.

Karlach is fun. Though I feel like I'm missing out on most of her story and personality by playing her as main, since they made the main almost a silent protagonist compared to Divinity 2. :/

I decided on only having a party of prefabbed characters, which I like. There's a nice weave of narratives, main character aside (aside from the occasional frown or rare smile)

Dark Urge is for the PC only I believe.

I just made it to Act 3 playing as Wyll and it's been cool. Not a whole lot of content so far compared to the other origin characters though
