How do you all prefer to use spies? It's obviously situational, but I have a few things I waver on with them. I'll obviously use them for the necessary tasks (sabatoge spaceports and such), and always do the +2 levels mission before a real mission, but the things I'm not sure on are: 1) To use them vs friendly (or neutral/friendly leaning) civs who I might gain more from, vs only using them against enemy or denounced civs. The negative modifier for using spies and getting caught isn't very high to begin (only -6 iirc), seems like if I've got a very solid relationship with someone, and could steal a great work or nice tech from them, it's worth it, but I tend to avoid this. Thoughts? 2) How often do you all like to use them defensively? I think I under utilize this, but unless I'm after a space victory with one obvious target to defend, it seems like kind of a waste. Sure, I'll defend this theater district or commercial hub in city A. Whoops, cities B through G also have both of those districts also, I feel like I'm still very close to as likely to get funds/works stolen as I was without my defensive spy! So, do you guys use them very aggressively, vs whoever has the shiniest loot, or more strategically and defensively?
