Oh, yeah, it's really good at that. If there's a (as in singular, rather than many, often working at cross-purposes and/or unaware of each other) large (as in 'could deploy 100s of agents to fight the PCs') government conspiracy, it's not designed for that, and I think you'll need to chunk that 1 conspiracy down into a dozen or so sub-conspiracies all with mildly-different but interconnected goals, though.
