MetaBuff would buff any placed buff, by modifying the duration or the effect.

Imagine a buff that doubles the duration of an already placed buff.
Or a buff that doubles the effect of an already placed buff.

For example, a Metabuff could extend the duration of a Stadium snack from 24/36 hours to 48/72 hours.
Or another Metabuff could increase the effect of a Machine Oil from +400% to +600%.

Instead of creating more buffs in an already crowded star menu of buffs, Metabuffs could make it simpler for players to choose the exact kind of buff they want. Metabuffs would be widely traded since they are so versatile.

Zone buffs are a kind of metabuff, but they only affect specific groups.
Metabuffs would enhance any one specific workyard or building.

How would you get Metabuffs? You could use the Snack shop or Laboratory, since this would give them to everyone in a controlled manner without flooding the market.

Buff your buffs... with Metabuffs!
