"
2" is the multiplier of rank and influence points from quests and battles (you will gain up to 2 times more influence and rank after each quest and battle than in original game). If you set it "
1", it will be identically to the original game. Of cause, you can set it higher than "
2".
For example, if you set the multiplier "
10", you will gain up to ten times more influence and rank after each quest and battle. But it will not be interesting game - "too much love will kill you"

.
New game is not needed.
