I would like to see this. I should put all the ideas I have down for this and also design some mini-games.
How I think it should be done: Set it in 195x Use the detective style of ICFTD as you try and find plans for an Alien invasion. You can play as Jane or Dr Barnstorff.
Next, use the strategy map play from ICFTD to defend against Alien attacks.
Then you take the helm as RR and fight in various arcade mini games and you can lead a rocket man assault on an alien outpost on the moon.
I've got some more ideas written down, I will try and find them.
