You know...
I love it how people rail against WCSO being a seperate game, when a) it doesn't require WCP to operate, b) while it's a continuation of the WCP storyline, it is a seperate storyline that can stand without WCP even considered (much like, say, WC2, which even idiots haven't claimed is just an add-on to WC1), and c) the WCSO plot that people claim isn't there compares favorably, in terms of quantity and quality, to the plotline of WC1, which more than a few people have said was a good game.
Of course, you (generic "you") are free to think what you want. Much like thinking the sky is pink with blue polkadots, though, thinking WCSO is an add-on doesn't make it so.
