Thanks Mord, I appreciate the response, although I'm a bit puzzled by the necessity for customers who want the 2nd CM:BN module to purchase both an upgrade and the module, if I'm understanding you correctly. It would make a lot more sense to me for BFC to include the upgrade with the later module (with an option to by a stand alone upgrade for those who don't want to shell out the full price for a module they aren't interested in, but who still want the latest and greatest version of the CM:BN base game).
I'm a great fan of the CMx1 family and I certainly don't begrudge them trying to extract a higher return for their work. I probaby got more game play value out of the original CM series than any other game I've ever owned. Nonetheless, the new plan sounds like they may be slicing the salami a bit thin (to resurrect an old metaphor). I suppose the test will be in the pricing and content offered with the new scheme, but even best case on value, it does seem like it's going to lead to an awful lot of fragmentation, with various base games, modules, packs and upgrades. Time will tell.
