Didn't they already run this scenario once before a couple of years back?
Can't come up with anything new? on the real real real real tip , not meant to offend here, but a serious question.
I'm guessing that you haven't played in scenarios yet and aren't yet familiar with them (or you'd know the answer). Just like with your question, this is not meant as an offense, but just an observation. So for you, it will be new regardless. It would be excellent if you come play in this one -- I think you'll like it.
To explain, scenarios historically have almost all been new. Below is a list of which were new and which were rerun. Now that we have a good list of proven, fun scenarios, we will probably run a higher proportion of proven designs, rather than a new one every time. This is for two reasons. First, players ask for various scenarios (such as Rangoon) to be rerun because they liked them. Second, we want to run at least 3 scenarios a year, and for doing that with our small group of player volunteers (we're just regular players like you guys), we can't do 3 new ones every year.
A new design takes concept (which is the part that is easy, quick, and in great abundance -- so, no, we don't have a problem coming up with new ideas) and then a bunch of just plain work: fully fleshing out the rules and scoring, writing the rules into a document that is clear without loopholes and inconsistencies, making the terrain (if we don't already have it), determining play balance and scoring, then multiple test/debug cycles. This work part takes collectively more than a man-year to do (typically 4-6 people for 3-5 months of their available volunteer time).
Here is list of past scenarios, with notation on which was new and which was rerun:
Rangoon, '42 (August, 2008) -- rerun, last run in 2004
Der Grosse Schlag (October, 2007) -- new
Operation Husky (June, 2007) -- new
Battle of Britain 2006 (September, 2006) -- rerun, last run in 2004
Operation Downfall (July, 2006) -- new
Stalin's Fourth (April, 2006) -- new
Fire Over Malta (November, 2005) -- new
Coral Sea (April, 2005) -- new
Rangoon, '42 (October, 2004) -- new
