The SCW mod was for CM:BB, but it was more than just a few scenarios, if one was so inclined there were enough mods to justify a second CM:BB/SCW install (I had one and loved it).
Not true....They looked fine if you had enough mods, mine even sounded fine.
There really were a lot of mods for this one, IIRC there were a couple of dedicated websites too.
PS - I believe I've still got a fair number of the scenarios, but sadly none of the mods (I may still have a hard drive with all of it somewhere).
