Arcane
To be honest Arcancum completely broke for me when I realized I could scum switch realtime/turn based back in the day.
Might be a good time to reiterate my philosophy is basic;
Elvira felt atmospheric - keep.
I like EoB combat best - keep.
ADnD 2e was my edition in high school - use.
Lastly - make something unique because if not what's the point.
Sure, the only problem i have is that i subjectively dislike EOB combat and also think it's objectively bad. Combat based mostly on the ability to press buttons on regular basis - and i don't even mean button(s) to attack but to "dance" before enemies - is bad. Still, i respect your choices, at least you seem to know what kind of gameplay you are after which is more than some other developers. And the game does look very atmospheric.
