you better mention it or just not post the comment at all as it has no place on a discussion about the actual shadowrun world.
Really? Would you like me to ask your permission to log on to my computer as well. This is general Shadowrun discussion. I'm pretty sure "the rules" is further down the page. Whatever dude.
I said it before, there needs to be a basis of reference. Without anything else modifying the conversations, people entering into the discussion are going to assume you are talking about the unmodified rules as written.
If you are discussing something else, it it just common courtesy to let the other folks you are talking to know this.
If you jumped into a discussion on chess, the assumption would be that you are discussing the standard chess rules. If you wanted to discuss a variant you had come up with, you should start off saying it's a variant, not just jump in as if it ere part of the regular rules and then act all surprised when people get confused.
Really, at heart, it is about conveying your message effectively. If the person you are talking to does not have the same frame of reference as you do, any discussion will inevitably cause confusion and lessen the impact of what you are trying to say.
