I am and I think it is because of origin characters. I get it - Larian has a finite amount of dev time and the origin characters are going to take a ton of work compared to characters like Halsin, Minthara, Minsc and Jaheira.
But let's say they take 2x as much development time (which seems generous, I imagine it is significantly more than twice as much development effort) - I would much rather have 16 well fleshed out companions (if they can develop two companions for every origin) than 6 origin character and 4 companions.
But that is also because playing an origin character is not super appealing to me. I have a little interest in playing Wyll and Gale, I suppose. But I'd much rather just have more companions to make each play of the game unique rather than playing as a predefined origin.
I loved, loved, loved DOS2. It is in my top 3 favorite games ever. But playing as the origin characters didn't click with me. Maybe it will be different with this game.
