It will interesting to see what 'Vic' comes up with per implementing more options for victory conditions.
With the plethora of data & statistics this game offers, there are numerous paths to victory one could allow for.
Scoring per military strength/results, research, population, territory, politics, moods, etc, etc, could allow for a variety of game challenges.
This could be in the form of options or, simply, the overall combined factor to determine ones final status.
Using scoring methods to determine a winner as opposed to all out conquering is a tried & true formula for most games & I am looking forward to what the future holds for this great game in this area.
