Welcome to another (or first) edition of "Did you know..."
Standing in for a dialog with a "show me more tips" checkbox is your host, me with a series of fairly random but hopefully useful suggestions that might make your gameplay more fun!
#1 You can "grab" the map with the left mouse button and move it around by holding it down. You may never want to edge scroll again.
#2 You can RIGHT-CLICK on the ship built block notifications that flow down on the right and your ship will automatically be launched.
#3 On the planet screen, you can put your mouse over the approval and influence and it will explain where that number is derived from.
#4 In the Diplomacy screen, you can RIGHT-CLICK on tiems to bring up a dialog that gives info on that item.
#5 You can play a quasi-Hot seat game with someone by loading up the game as GalCiv2 cheat (use the cheat parameter). Then when you set up the game, you let the AI play out a few turns and then have your friend pick one of the races they want to control. Have them select that unit and hit CTRL-SHIFT-Z.
#6 CTRL-S is the quick save.
#7 You can double click on planets and various other items to take the place of having to place, or install or build or go to their screen.
