Revelation, you need to get your research much higher
1. Get Comm to lvl 20
2. Research Viators, then Viators 2`s ( land is they key for a successful terran empire ) if you don;t know how to get this go to restart, click on terran then look at the research list
3. Research Cluster lvl 1 and 2
4. START EXPLORING ! You want to keep only single planets over 800 land, and you want to find 1 or 2 U larges, these are super large planets which as unpaid can be up to 10k land
5. get a c-2, at least 20,000 land, and you should be making a nice income, then keep exploring for U class planets and maybe build another c-2
6. PATIENCE, this is gonna take a while, but your planets are very important as high land for a commercial terran, so it is worth it
hope that helps matey
