Considering the potential epic deeds magi can do, their impact on Europe seems very minor. I accept part of the game design is Bonisagus and the founders wanted to keep in the shadows. The hatred the gift engenders makes caution and a low profile logical.
I'm not talking about setting up Magi kingdoms, magi outreach programs to cure leprosy, etc, I'm talking about side effects of Magi actions.
One example of actions with potential side effects. Travel and exploration. A magi with commitment could upgrade 7 league stride to take a cart or wagon, and be Marco Polo. A Verditus could craft a ridiculous boat making the Santa Maria look like a raft in comparison.
It seems peculiar this hasn't happened, and certain consequences of such exploration and discovery haven't happened. Bok Choy being a staple vegetable, access to fireworks, silks, etc.
My thoughts are, the AM writers chose to keep magi side effects minimal, as bok choy as a common vegetable, fireworks, silks, etc, break the Mythic Europe theme somewhat.
Like with any AM, the RAW are a starting point. The books and especially this forum suggest go wild, and change whatever you want. I'm curious for those who have kept the setting close to the RAW timeline, what tweaks you've added to Mythic Europe based on not direct magi action, but side effects of their actions?
