We would be happy to have you on board
I'm not sure I realized that the campaign was that big, so we can certainly revise the speed of play. The important thing is that the players are committed.
I would prefer the version without superpower intervention.
Regarding optional rules: We are amenable to any optional rules except "no locking zones of control," which I don't believe is even available in ME 67. My thought with offering the _alt rules because (a) they seem to be widely used in the community, and (b) since Volcano Man designed the scenario, it seemed appropriate. But, if you have a suggestion, I don't see why we can't accommodate it.
Regarding the IDF's high interdiction rate. I would certainly be open to modifying this, especially if it resulted in a better game. I have no idea how to do any of this, however, and would need some help.
Feel free to contact me here or at my email address if you want to discuss matters further.
OJW, feel free to chime in if you have thoughts of your own
