First off, I do not know how D&D would work in these situations. There are a lot of conversations where you need to convince someone else of something. Usually there are options in brackets like persuation or intimidation. Each choice like that results in a D20 roll. And sometimes, you have no choice but to choose one that ends up with a roll. However, if the roll fails, you are stuck. There's no additional conversation and no choice usually other than to attack or leave. This has happened to me often enough that it's noticeable and annoying. Since it's not only an RPG but a game that's supposed to be fun, I'll sometimes end up reloading a save game. I know that's a no-no for a purist, but as I said, my preference is to have fun.
I suppose one could argue that it's like that in real life, and as I said I do not know how D&D works, but I still think I should have other options. Just my opinion of course.
