I would love to see some sort of generic scenarios first... (Capture the objective, cross with the prisoner, etc etc), that you will be able to play no matter what force you have... then in a second part mini campaigns, let's say 4 or 5 generic scenarios linked together to form a generic mini campaign...
For example: First Battle: Recon (Rumours of a powerful artifact), Second Battle: Capture the Objective (We have located the artifact!), Third Battle: Annihilation (We both want the artifact and I'm not gonna give it it to you), Four Battle: Escape with Objective (They got reinforcements!! We need to deliver the Artifact to a safe place!!!)
Hope the idea sounds clear :P
