A spy simulator. The overworld map would resemble Hearts of Iron, with various nations and organisations trying to dominate each other militarily, ideologically and economically, and with grunts like you working behind the scenes to acquire information for your side and to prevent information from being taken by the other side.
A more personal, day to day interface resembling something like LCS would be where you allocate actions per day/week/month. Obtaining intel and playing the long con while evading detection from whatever organisation your infiltrating as well as counter-espionage officers and other spies. The information you obtain could be just useless chatter, or be the crucial bit of info that gives the higher ups enough of a push to give that invasion or uprising a go ahead. Actions that one could perform while infiltrating other than feeding data would be turning agents to your side, bits of sabotage, and very risky assassinations.
Over time, you can progress from being a singular spy in an espionage ring to running the ring itself, recruiting agents, testing their loyalty, persuading defections, all on an increasingly grand scale, depending on your success rate and ability to play both the internal politics of your government and the internal politics of the spy community.
The world would obviously have to be very fluid and act on its own, with your entire job being to report on happenings not known by your side, and adapting your side's knowledge by as much as possible, as accurately as possible. And of course, not getting killed.
