Capturing planets in Simultaneous play

[BeeDee10]

Personally, I would give the first option a shot; 50M isn't all _that_ fragile a population. I've found that the most "surgical" weapons to use against planets are direct-fire weapons, if you use seekers then your ships will fire a salvo that will deliver overkill damage whereas with direct-fire weapons they stop firing as soon as the weapons platforms are all gone.
