In my rule book it specifies for Maecenas that his power is limited to the recruitment phase. Since Rome's extra leaders are not played during that phase, Maecenas' power should not apply there. This would mean that for Rome he would only be a 1 or 2 coin benefit for the value 3 or 4 leaders in 2nd and 3rd recuitment phase.
Bump for this tread. I think Martin is right. In my English rule book also states that Maecenas power is applicable in recruitment phase. Otherwise he could be too powerful for the Rome player.
Please give an official answer.
