Unit "gifts"

[sophist]

Under what circumstances would you want to gift a missionary? I can see two. You want to get rid of the support cost, while still deriving some benefit, and you want to target a civ that has closed borders with you but open borders with a third party. I don't know how you could get an AI recipient to use the missionary on the specified target, though. Maybe if diplomacy included an agreement whereby you could agree with another civilization to try to convert a third religion to your common faith (or any other, for that matter). It would still be useful in MP, regardless.

The tactical options on this in SP are great. Perhaps you can aid with units without opps knowing about but don't have to fight the war.
Or perhaps the opps always find out making them eventually pissed off on you.

I just hope that the AI makes use of this feature too. I'd much rather that they gift me their units than have their units crawling through my territory.

According to the previews I'm seeing the AI DOES USE THIS to help you at times.

But only if you NEED help. Probably happen more often while you are learning the game and in dire need.
