Exile,
Success is in the eye of the beholder. If you set out to get all the movements so that they would be 'right' and all coherent to make sense and as historically accurate as possible, then yes, it is a monumental failure...
However, it is a success, or so it seems, in its playability in PBEM games. And this is not something to ignore in my opinion. True, the problems of getting things accurate and balanced at the same time probably is insurmountable in civ. For that, yes, it is a monumental failure.
But if you ever come to terms with these problems and wish to work, not against, but with them in some way, I will be very happy to see any official Exile produced modifications to AoW. If not, I'll still enjoy it!
And that is my two pence, for what its worth.
Keep on civ'n!
