Glad you posted your intro finally David.
I was not aware you don't like looking for scenarios.
As far as categorizing them by balance, I have done that very thing with some simple lists I made. I think one is called "most balanced / unbalanced WF scenarios" and some include minor notes, like what scen has been modded, if it could use a revision, etc. I'll get around to sending it to you sometime.
As far as determining difficulty on the scenario list, Roadrunner has a point. Just be sure to remember to take into account the "games played" stat that shows the number of times it's been reported. If there's only been a few playings, there's no real way to tell how balanced/unbalanced something is. And the only reason I made my own little list is because I like to see all scens "at a glance" without having to flip through a lot of different pages. (it took me almost a week to type it all out though...ugh)
Finally, keep in mind that some players, like me, prefer to play the "disadvantaged" side...it's more challenging, and more rewarding if I win. This can skew the balance ratings on the latter somewhat (because normally, the tougher side should usually lose).
Talk to you soon my good man.
