Alan H. said: My advice: Explore with these players why they want to play that alignment, and how they see it playing out within the group. A simple discussion, rather than being kicked without any real warning why, is much more productive and will stop these players being annoyed at you as a GM. Create a game where everyone including yourself has fun, by drawing on what they wanted to achieve, not by second guessing their intent (for example you call then trolls and imply they intend to ruin the game deliberately). Maybe ask yourself where the disconnect is between you trying to emphasize the team aspect, and the players you invited to the game choosing to play "diabolic" characters? And why you did not address it with them when they raised the suggestion? However, I think such discussions are off-topic for the Roll20 forum so to bring this slightly back into focus, Roll20 is a big community but still a finite pool of players and GMs. If you want to GM for lots of different people I think it is important in Roll20 to approach games in a collaborative, communicative manner. If you are opening your game up then you might come across players who you would not enjoy having at the table, or who do not mesh with the style of game you're running, but it doesn't make them bad players or "trolls". Yes I suppose calling them trolls was a bit rich, the last player I was trying to work with was not even remotely invested in the game and I could only get 1-2 word answers from him. I did actually address the Alignment issue with both players in question, the least player informed me that "I'm gonna get people to see things my way ". Probably fine in another setting or genre but simply could not work, it would be like having Hannibal Lecter on the set of NCIS. I did not realize that I failed to put that info into the original post, was having a few connection issues last night and the post that is up there now ended up being typed several times over. It appears that in the process I left a fair bit of information out of the final submission. Anyway wanted to thank everyone for their suggestions, since reading your posts I have taken the Forums advice and tried to refine the guide lines for joining my campaign so that everyone is on the same page. I have also viewed some other campaigns joining instructions as a guide in order to bring my own up to scratch so that there is no ambiguity.
