I just stumbled upon a great resource for scenarios - seems to be for Warmaster but they could be adapted for anything. I always enjoyr eading other peoples house rules and special scenario rules so I was pleased with these. Especially the link for Bencon seems a treasure.
A picture - just because each post needs one :-).
