Okay, I just bought this game today and after playing it a small amount, I have a few suggestions on how to improve it:

1. Allow us to change the resolution and choose between fullscreen and windowed mode. This is a standard feature that's expected on every game.

2. Add a real "quit" button. Not having one feels wrong and extremely amateurish.

3. Let us play the skirmish mode whenever we want, instead of forcing us to complete the campaign first. Most people who buy games like these aren't doing so for the story, so locking what's likely the primary reason for even purchasing this title is a huge mistake.
