While there is no fleets, but player 1 have:
1. 26 level in all fields
2. all MT toys available
3. all his planets filled with as many mines, factories, defences as colonists can control
4. all his planets has 1.000.000.000 kt of each mineral
5. additional 100% planet around each of the players HW

And new designs and fleets can be added as well.
