Sorry if it’s here and I missed it, but one of the biggest reasons it feels just like DOS1/2 to me is they’ve used the same font throughout. Same font with same outline effect, at the same sizes for all three games. The dialogue choice list during conversations follows all the exact same layout too, down to how the tag options are presented eg [DROW] and the same use of asterisks. Definitely makes it feel like a DOS sequel.
