So I wondered: do you plan to make the satellite do the same thing as in civ 3 ? It says it reveal all the fog, but in tt2 it wouldn't be very useful that late because by the time someone reach space age the whole continent is already revealed by alliance and seeing others continents wouldn't be very useful, it would only unlock a lot of naval POI instantly.
Actually, player can temporarily quit alliance, finish that research/unit and find all possible POI, then rejoin alliance after cooldown is over.
