If you want to make the game slower paced why not just double the amount of planets rather than reducing the number of attacks to take them.

[Ze_PilOt]

Because it's the alpha and I don't want to redo the galaxy at this point.

And 10% was the value I had it mind, even with a bigger galaxy. I've increased it to 20% due to the low number of player, but it's seems not needed.
