In usually prefer flat checks in computer RPG - that said Disco Elysium used skill rolls extensively and it felt great. Josh Sawyer (Obsidian dev.) mentioned it in his reponse to BG3 checks. I think I too prefer bell curve, as extreme successes and failuer are rare instances indeed.

- easy lock he will succeed 19% more times compared to times he would succeed without those modifiers.
- medium lock he will succeed 64% more times.
- hard lock 116% more times.
- very hard lock 700% more times.
