I can't really give a good, detailed list, as I will probably leave something out. I'll just leave it at: I like robotics, science fiction, some fantasy books, construction kits, video games, and reading. That's better than my previous list....
Don't worry. I haven't abandoned the Alien Conquest RPG. I plan to continue it. Right now, I am just trying to think of a way to incorporate Galaxy Squad, like I promised Zakar0%, and Mars Mission. Don't worry, I won't let it die.
It's simply good strategy. They also could have done that before the invasion, built up their forces, and dropped hundreds of thousands of troops and ships on us at once, thinking we would be overwhelmed by sheer force of numbers.
av, you might want to check up on the Planning Topic. Mars Mission is being planned as an RPG by Kaithas. (Sort of) You should contact him about your plans.
