Hi Glen,
I think that your suggestion about different victory condition could spice things up.
Surely they are worth the read.
At first approach I can say that in some scenarios (as you say in Condition #1) Limit # of Turns could also be good for "siege" scenarios... or in these maps where one army is too powerful than the other.
Victory Condition #2 is something similar to these scenarios like "if Army 1 manage to defeat Leader 2 it's an immediate victory". There should be some scenarios with Scipio in this situation.
I think that adding also "troops" condition could change the game too much, but surely I'll give it a try.
Gaining VP for keeping some hex in the map during the battle is already available in some official map.
Maybe it could be used a little bit more for some "strategic areas".
I'll keep both of them in my mind during my next scenarios (there are some other in progress right now)
