I think this is also worth reading, cuz you can gather up pretty much everything you need to know about the wildstorm universe in it's image years.
Basically the facts about the war that the wildcats dicover on khera, changes the comic kinda completely. Spartan and Grifter go into that big corporation thing, in vols 2 and 3. And I like those stories cuz they're no longer about a superhero team, and aren't written with a villain they have to fight each arc.
and once you know about Tao you know all you need to know to dive straight into Point Blank and Sleeper. Lots of sean phillips goodness.
It's still Moore, I rate it above any other wildcats from the first volume. They hold together pretty well, if you ignore the crossover issues, there's basically 2 stories. Wildcats in Khera, and then the brewing gang war.
I think you found this tpb cheap cuz they've re-released all his wildstorm stuff together in one hardback.
