Cannibalism (New Special Abbilities)

[Agent-Jay]

There should be some UU regaining hitpoints after winning a combat (breakfast time ), or giving some other bonus, maybe giving culture points to your capital. Or Food . You know, enslaving/sacrifing isnt very nice too. Or, in case of cannibalism add unhappiness to the defeated Units civ...
Another option, similar to ensalving, taking hostages and getting money for them.

Not bad, I kinda like it.
It'll be one of those 'do it youself rules' I think though.

could be something like capturing POW's. could be a unique unit that could be sold back to orginal civ, used as slave workers (possibly an exception to the slavery civic option?), sacrificed for culture (if your civic options, and moral ethics allow that.... ) or used in something along those lines.
