Nah, that would get annoying.
One of the reasons I believe that previous Godhoods have suffered was because of too much of a category. For example, it was manageable to deal with a few races and sub-forms of said races. Then people were each creating their own little race to be their servants, which not only caused these new things for Caesar to take note of, but also made some of the other races to be neglected.
This is my personal suggestion on how to deal with gaining acts:
FIRST, there are Worldly Acts, or Acts gained as a reminant of Creation. These acts would start at 2 acts/per turn, then would lower to 1 act/per turn before eventually disappearing. Maybe it should degrade at a rate of 3 turns per level, or something similar.
Anyway, SECOND, there is Sphere Acts, or Acts gained as a result of a sphere. When mortals do certain things, they can glorify certain spheres subconciously, which will cause belief in the matching god to rise (covered later). IF, for example, mortals deal with the sea, the god of the sea would get acts, when ground is worked, acts for the god of the earth, murder for the god of murder, etc. At max, someone may gain up to 2 acts through this catagory.
THIRD, there is Worship Acts, or acts caused by belief. As mentioned above, doing certain things will make mortals believe in an entity more. While belief is nice, it is not worship. To prevent confusion, only the PATRON god of a community will benefit from their worship. Each MAJOR community of a sapient and free-willed populace will have certain act amounts associated with them. HOWEVER, these counts will not be high until you get to giant Capitals of a nation.
As an example, imagine 10 specific communities, where 7 are large (major) towns, 2 are cities, and one is a Capital of a civilization. A large town will generate about .2 acts per turn. This means you have to control 5 of these towns to get any significant boost to your acts. The cities, on the other hand, each provide .5 acts. That is another act every other turn, and a full act every turn for dominating both of these cities. The Capital itself provides one full act; this in itself makes it very powerful. Of course, as there are more than one god, gods will have to attempt to dominate the regions they seek to get these acts, and will probably not get any at all. True dominence is needed to get these acts.
Finally, there are Power Acts, or acts gained by effects of some sort of force. A monolith, an obolisk, a pyramid, the like like that designed to take in natual energy. While these constuctions woruld be diffucult, they would be a stable act source.
