Hey guys. I've been out of the RTW loop for a long while. My comp wasn't very good, so I stopped playing it. Now I've got a good one, and want to start again. I've been looking around, and I see mention of an expansion pack in addition to BI (at least, this is what it appears to be). Is it any good? Worth buying? I don't have BI, so is that included in it? I want answers, rebukes, facts, opinion, the whole bit, and the kitchen sink, please.
