Galaxy on Fire is an ingenious space simulation. One can explore a vast galaxy. There are tens of spaceships and equipment. You start with an old and rickety spaceship, towards the end you can not afford large battleships. There are many ways to raise funds. Trading in goods, mining of raw materials, bounty-hunting, fight against pirates or escort missions. The story is also quite nice, and the graphics I found really good for a tablet game.
Highly recommended for those who have previously enjoyed playing Privateer, and always wanted to have an own spaceship.
