We’ve talked about this quite a lot and come to no conclusions.
Basically being allowed to make an agent which has a set effect on all species is much too powerful, it just becomes “kill juice.”
The way round this is to have each agent have a code and each organelle have a code and those have to match sufficiently closely before there is any effect.
The question then became how many different agents should you be able to store and should you be able to produce new ones on the fly. Moreover how do you manage this large amount of agents.
I think that was as far as we got.
