Was thinking today that having a booster that caused to action to happen to all of your planets might be fun. For example, player has 6 planets, and triggers "platinum" booster. This would have the effect over all planets. Probably best for just mining boosters, and would likely have to be expensive in comparison. You wouldn't want to waste it on 1-2 planets.....
