@bobinot: A couched lance has the potential to do a lot more damage than a thrusted one. In multiplayer, it's often used as a 1-hit-KO technique or an effective shield smasher. It's also useful because it allows you to keep your shield up, so you're less vulnerable to missile fire. However, its uses in single player are limited by the fact that it has shorter range and depending on your gameplay settings, cannot be used constantly, like thrusting.
No clue about city giving, sorry.
