I'm wondering with World War Hulk having so many limited series titles linked to the event as well as several tie-ins, is a reading order necessary?

Marvel does provide a checklist with the order of each WWHulk involved title in their release order, but is it crucial to follow the release order?

Do I have to read WWHulk: Frontline #02, then move to Iron Man #20, then Heroes for Hire #12, etc... or can I read all of WWHulk: Fronline together, then move to WWHulk: Gamma Corps, then to WWHulk: X-Men?

The Paperback releases are seperate: WWHulk #01 to 05 is released on its own. WWHulk: Frontline #01 to 06 is released on its own and so on and so forth. That gives me the impression that I can read each limited series seperately without skipping from title to title every other issue.

The one true fact I know of is that it all begins with World Breaker. Being appropriately titled World War Hulk Prologue, there is only one spot in the order you can place it in.

If anyone can let me know if it's safe to read each LS seperately or if it's crucial to read them in their release order, it would be very appreciated.

Thanks
