COuld someone plaease explain how exactly conversion (one Empire surging converting another one) works? Thr costs, the number of pieces, etc? I thought the rule book to be not so cloear on this issue. Thanks!
You can only convert units when starting a new empire, and only if the empire card allows it. Converting has the following effects:
1. The units, fortifications, and leaders present in the starting area(s) now belong the the new empire. Units with colours are immediately replaced with eqiuvalent units of the new empire's colour. This is in addition to any units purchased with starting money.
2. Any city present is not reduced or removed.
The nitpicker's guide (http://boardgamegeek.com/files/thing/3870) might be helpful.
