We have a few inspirations more based on the individual developer. Arbuz is looking back at his favourites, Baldurs Gate 2, Fallout 1 and Fallout 2, Divinity OS2. I personally look back at games like Shadowrun, Fallout 1&2, Final Fantasy Tactics, Nier Automata etc. Every developer has their own inspirations to what they work by. Even from board games like Kingdom Death.
However, we're not attempting to adapt or take anyone else's world or stories of course. We've more or less focused on learning lessons taught from other things and applying those lessons and some of the ideas that stuck with us over the years. The world for instance is completely ground up out own.
