I can very much recommend looking at games developed and published by Wadjet Eye Games.
You can see the learning throughout the years, with the Blackwell Chronicles being a bit linear, and some games in between being a bit of a miss.
But "Unavowed" or the new "Old Skies" are excellent games I consider on par with the old golden age. "Technobabylon", "Resonance" and "The Excavation of Hob's Barrow" are also very far up.
Yes Technobabylon was pretty good. Need to check the others! Thanks
