I think there’s a big difference between games that are pretty much adaptations of parlour games (like Articulate) and games that are based on maths where the mechanics have been carefully considered and have probably been playtested to the nth degree.
With the former the rules are up for grabs. Whatever makes the game more fun.
With the latter you better have a really good justification for changing the rules and even then it’ll need assessing over several games before I’d agree to a permanent change.
