I was hoping it was dark, i like dark, dark is good

I like it bright actually. May need to light this planet on fire to provide me with light.

if you realy want to mess with a planet find a way to inject iron in to the core of there sun and what that sucker turn in to a black hole

That's so drengin. It should be a game mechanic, its also very galcivy.

Then again, that may be how terror stars work.

Well, Gaunathor knows...

Why cant we develop 'Little Doctors' as used in Ender's Game and 'unzip' molecules in a chain reaction? Thus training our 'Little Doctors' on planets would be a very nice method of atomizing the entire planet!

Plasma Bombardment Halo Style does that pretty well, especially if you just lob the plasma at the atmosphere instead of directly on the surface. Sure in Halo they glass the planet, but that is only the end result, on the border between glassed and non-glassed parts of the area, there are massive firestorms. So if you take a less intensive approach then the Covenant does, you can set the entire planet on fire and boil off the oceans, for quite a extensive period of time before you run into issues like burning off to much of the atmosphere. (i.e. after a while, the entire atmosphere becomes hotter then the ignition temperature of oxidizable shit on the surface, long before you reach temperatures that would melt the surface.)

Probably more economic way of doing it compared to conventional methods like firebombing/napalm/thermobaric weapons.

We only understand a fraction of elementary forces physics. It's entirely possible that someday we will be able to manipulate the strong of weak interactions and literally break shit up into atoms or subatomic particles. Of course changes of this being energetically economical are slim.

Luckily for us we will probably be able to manipulate gravity long before that, and do the stuff Sandra thinks off in Ender's game, like reflecting a planets gravity back onto itself or parts of itself to rip itself apart.
