What exactly do the terms "plot wagon" and "plot hammer" mean, anyway? I've seen you use them before.
Plot wagon: The DM's steering of the party along the plot. Good players will go along.
Plot hammer: As above, but the party has no choice, and is usually a spectator/slave to the plot, rather than the center of it.
Ah. I'll try to keep that in mind for when I DM.
Players that deliberately overturn the plotwagon are usually either too used to plot hammers, or total dicks.
I was initially going to say that my group is like that, but upon reflection, of the people I play with:
1 likes to play a barbarian, have ridiculously cool gear, and kill shit,
1 likes to be a dainty wizard type and worry and fret about the rash actions of the party,
1 likes to play high-charisma characters despite having absolutely no charisma himself, to the point of not even being able to roleplay a pleasant conversation,
and 1 is as the above barbarian, except that he always takes Chaotic Evil for his alignment.
That last one causes surprisingly little trouble, despite his habit of doing things like going into schoolhouses armed with a greataxe while class is in session.
Myself, I like to play spellcasters who do their best to keep the Chaotic Evil guy and the Charisma guy from getting into serious shit. Me passing off Charisma guy's complete lack of social skills as "assburgers" to guards has even become a running gag. We all have a grand old time.
