Well you can start by getting at least 2000 gray bricks, and at least 10 gray baseplates and 10 green baseplates. Build a wall on the baseplates. You can make sliding doors and scout towers. Get some clone walker battle packs and other Republic vehicles and put them in. Make a command center and a barracks. Check out Michealmjf's vids on you tube for more info.
