I'm going to threaten to withold funding from another player's d&d character's pursuit of their ultimate goal
Don't you think its rude to make threats to withhold funding?
Please don't be so naive :P
Well, I don't really know much about D&D but to me it sounds a little mean-spirited to take these sorts of actions against them. If it's all through the role playing, I guess it's okay. Just don't let it get out of hand.
I just want to ruin the game for them for being a bad sport.
If it's the case that this is reality, then I do believe you shouldn't try to do such things. What about the other players, do you think they're going to have a lot of fun with this kind of drama spilling out?
