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.

Eh, when it comes to puddles, I am quite sure there are already mods to remove those from certain spells. I don't like how puddles are implemented - they adhere to D:OS2 ruleset, not D&D ruleset, feel out of place and don't play nice with other mechanics, like concentration.
