That seems very fun, coupled with the fact that it's essentially a desk top theme to an existing game instance/map as opposed to new content whole cloth. And far more thought out than my own notion other than "it's magic', Neuron telling you "I've made this thing which if it works could prevent the loss of First Ward. But none of my clockwork come back. (He's built a time device and isn't actually trying to get to Cim) you're expendable...ah.. courageous, grab some of your friends and find out." Then post mission he's all "what thing? Time travel sounds like something Keyes would do. He'll do anything to get his praetor job back. Supers from another earth? Nazis? Oh they weren't actually Nazis. Right. I don't have time, get it? ,to deal with this. Get lost.'
Thanks for all the answers so far! It does just boil down to loving Praetoria and still wanting to team with your friends. Yes, taken the leave route before, that's fun too. I just think there should be the option of staying and playing rather than staying and mothballing.
