Your assumption #1 is in bold, your assumption #2 is in red.
As I already asked you:
Your assumption #1:
"I don't believe they ever made a promise to add new questions and answers to the FAQ thread".
See the title of this thread (written by 2K Greg), i.e., a solicitation for "questions/concerns for
inclusion in the FAQ", i.e. a promise to add new questions and answers to the FAQ thread.
Your assumption #2:
"merely show us the FAQ on Steamworks they had aquired and answered".
They have not "answered" the Steam questions yet. This thread and many others are filled with unanswered Steam questions. Please provide any supporting evidence that the promise made in the title of this thread has a time limit or expires or is no longer valid or is completed. I already provided evidence to the contrary of your assumption in that 2K Greg left this thread open (still soliciting questions) and the forum moderators still move Steam questions to this thread.
Yes, I assume that 2K wants Steam questions asked based on the fact they created, and still currently have, two threads requesting we do exactly that.
Fact?
The first post on this thread in which 2K Greg promises he will answer questions:
Above is 2K Greg promising to answer "questions and concerns" on this thread but he hasn't answered a single question from this thread for six weeks now and has never added a single question to the FAQ since it was posted a month ago. EPIC FAIL.
Your claim makes no sense. Why would 2K Greg open this thread soliciting questions and then ask other forum members to
please refrain from trying to answer other people's questions or start discussions about things other people have posted unless he was planning to be the only person to answer questions here?
Since he was the only one who would be the question answerer then if he planned to only answer questions until the FAQ was posted then it would make sense for him to have closed this thread once the FAQ was posted and he knew he would not be returning. Having a thread for questions, but without anyone to answer those questions (2K now absent and others told not to answer) makes no sense.
Now THAT is comedy. You really should go back and read your hundreds of posts splattered all over the threads of this sub-forum. Have you ever made a single post that wasn't strongly pro-Firaxis/2K/Steam? If so would you mind posting them for us?
Please provide even one "fact" that is in opposition to a statement I made.
Thank you.
At this point I strongly doubt that despite my great efforts that my question will ever be answered. But I also strongly doubt that 2K will ever be getting any of my money. I love Civ and that saddens me greatly.
