On the matter of who gets invited, you don't have the right. The guy who "owns" the place does. Your rights as GM starts and ends at the game, and only the game. Remember, you are a referee, not a lord.
Just because someone offers to host the game at their place doesn't require me to accept that invitation though.
How can you strain someone else's relationship? Guy already dislikes him intensely. It can't get any worse.
I don't mean between Guy and LilBro. I mean between Roomie and LilBro and Sister.
Asked her like I said.
[Roomie]: interesting topic
[Roomie]: I think...[lilBro] tends to hold grudges
[Roomie]: I mean, we don't have to play at [Guy's] house
[Roomie]: and [Sister] is VERY protective of her brother
[Roomie]: she WILL take his side
[Roomie]: if it comes down to that
[Roomie]: as much as I love them....I'd almost rather do option C....it would be a little calmer....
And then got ninja'd (I take too long when posting), so showed her your post too, CG.
[Roomie]: um...[Guy Friend] probably will be less of a dick in the long run than [lilBro] because he hasn't learned how to grow up
[Roomie]: he's never had responsibility so.....
[Roomie]: [Guy Friend] just doesn't get along with some people and no matter what he just can't get past that initial reaction to them
[...]
[yeller]: BTW, love how what you said earlier is partialy ambigous.
[Roomie]: how so?
[yeller]: I think it might actually sound like you're saying [Guy Friend] is the one who hasn't grown up.
[Roomie]: yeah....both of them really
[yeller]: So, neither have grown up...
[yeller]: Which does the "never had responsiblity" apply to?
[Roomie]: [lilBro]
[yeller]: Thought so.
[yeller]: So, [Guy Friend] is a mild dick in general, but [lilBro] was more of a dick in-game?
[Roomie]: yeah
For the record, I don't recall seeing Guy Friend interrupt the game with his dislike of LilBro.
