D&D
I've been playing RPG for decades, but play D&D less than once a decade, and my impression goes form awful to not worth my money/time. When I was young and broke, having to buy a player manual + a GM guide + a monster manual when tons of RPG would fit in a single book (Yes I know, clan-books for let's say Vampire are also a money-pit), was out of my budget, then every-time I played D&D, feel like the story were not interesting as concept like alignment and some spells like detect lies would kill many interesting plot. Too which you had a lot of character optimisation often over the long-term (If you didn't take that feat a low level you cannot have the killer feat at high level), let alone the people mixing RPG and miniature games
Sure you can have some funs game with D&D and play it differently but there is so many other game out-there (and so few time) , that why would I even bother joining a D&D game rather than another,
