Holy crap-- Space age is frustrating.
Some guise hate me and constantly attack my planet. Luckily I made allies with a guy who has an even bigger empire.
Also.
2 million sporebucks.
There was a planet selling pink spice for 10k, so I bought it up and took it to the planet nextdoor buying pink spice for 40k.
Sold about 50 spice. Made a killing.
4 million. And counting.
I feel your pain. You can't really get anything done with idiots like that attacking you. Therefore... you must eradicate them!!!
All you need is a shield and some good quality (medium to mega) bombs. Just fly onto one of their T1 planets (you don't even need the shield for this) and drop bombs on their single city. This kills it pretty quickly, and you can get the money and fly off without taking much damage.
Do this to every one of their T1 or T2 planets, then you can easily fly onto their main planet, bring up the shields, and destroy every city, capturing the system with little or no damage taken.
I have no more enemies in the area after this! :D
