Scenarios Feedback

I've completed one scenario and it challenged me to play in a way that I normally don't, so I guess that's been one good thing about it. To be honest; I wasn't impressed with the rewards, I'm not sure what I was expecting but it was something else other than just lifestyle points or whatever they're called.
Not sure if I'll be trying others in a hurry, I don't like the fact that I have to create new saves to play them and they can't be used on an existing one.
