Well, technically the WW2O team used to be the subordinates of the WB team; the heads of the WB team are now the Aces High team, which I play.
WW2O set some sort of record as the most overpromised game of history (a separate issue from most delayed)...they bit off about 90000% more than they could chew. I believe only about 10% of what was on the outside of the retail box was actually implemented in the game in the first year.
What didn't help was all the fanboys convinced it would be the greatest thing since sliced bread for months BEFORE it came out.."I'm quitting AH as soon as WWIIOL comes out, which will be the greatest game ever!"...then it turned out to have an arcade flight sim model and be focused on the ground war.
Don't get picky unless you're right ...
WB was originally the work of Dale "Hitech" Addink (who later headed AH), John "Killer" McQueen (later WW2O), and Robert "Gunjam" Salinas (who later founded Jackedin.com).
I don't think anyone disputes the fiasco that was WW2O's launch. I myself never got the thing to do anything other than crash during beta days; but that was then and this is now. WW2O is not the flight sim that WarBirds or Aces High is but I highly recommend it to fans of 'shooters' like Call of Duty et al.
