I figure if you can throw planets into other planets why not just throw your enemies into the sun . . . if you can get away with setting up enough halleys on the planet with the enemy commander on it, it would be their only silly fault. Just set them up and send your commander next door and prepare for the win
While tactical usefulness of this move is doubtful to say the least, I see no reason why it shouldn't be technically possible. Aside from the fact that planet should be really small to be moveable.
Um, I hate to rain on your parade, but why would you? The only planets you can move are so small that you couldn't build the necessary Haleys without the enemy noticing, and when they notice they would immediately send all forces to destroy them. I mean sure it sound cool on paper, but imagine trying to play a game with that.
because you need to make Halleys in the planet, and if you are making that, you have the planet, or is countering their halleys...
This kind of makes me wonder what happens (or should happen) when both players have enough Haleys on the same planet. Out of control planet that zooms all over the map?
