Space Exodus 2.0

[XHawk87]

Space Exodus currently relies on hacking the existing space race victory. While it was relatively easy to set up this way, it has drawbacks, such as:

• Required to display meaningless travel time
• No incentive to build more than a minimal spaceship as it doesn't add to score
• The player doesn't leave until the next turn when the achievement is granted

It might be better to switch off space race and instead create something new. E.g.

• A fuelling plant building with high gold upkeep that fuels the space fleet
• A launch platform building with high shield cost that is required in X cities, or X% of cities, of covering X% of population in order to launch
• A wonder that allows construction to start on these buildings
