Endless amounts of.. anything you want o.o
Traveling from a planet on a planet is awesome, finding new resources, battling, building special spaceships, managing diplomacy. It's a mixture of Supreme Commander, Rise of nations and Command and conquer with some originalities like the pathways and unfortunate limited traveling. You can't travel across planets any way you want, there is a special way to get to every planet and you go light speed to it, it looks awesome always.
Amazing game full of everything an RTS player would ever want, I simply have no critics except that traveling paths - if you had the possibility to travel any way you want it would have messed things up and you would have had to arrange it better all by yourself, which means harder game play and having to think more about that part of playing as well.
100 hours is a joke for this game, you can easily play 10h a day for a month and still not experience even half of the features the game offers.
