Now the thing about this game is that it poses a very interesting ethical conundrum: it's clear that from Big Eddy's speech at the beginning that people live on these planets, and what they think about their planet's temperature being changed by hundreds of degrees doesn't matter.
In addition, you have a beam which can both heat up and cool down a planet by hundreds of degrees in a matter of minutes - a massive amount of energy, comparable to a small star! You're telling me it can also suck away heat??
Now the big questions - who is Big Eddy? Why is he so big? Why does he want these planets cooled/heated? Where did he even get this super powerful ship from, and why does he need you to pilot it? Why doesn't anyone defend themselves? Is Big Eddy really an evil dictator teaching subjugated worlds a lesson? Is he referring to "customers" in the sense of people to be served a fiery/icy hell, or is he really a subcontractor under some other far more nefarious super-being?
And the biggest question: Would you kill millions for a quick buck? It's an easy enough job. Just push the right button for long enough, and you get swished to your next task.
Evidently, yes. Yes I would. If you did too, well, you have a lot to think about.
