My current game using d20 modern is X-files meets dresden files. In the game, magic ebbs and flows,and the tide is currently getting higher. Magic is slowly leaking back into the world and the PCs are part of an organization called Department 7. They go around investigating oddities and other events but have recently stumbled on to a conspiracy from a doomsday cult group that is gathering items for a ritual they plan to use to open the flood gates.
Also while avoiding government agencies who want anything magical related for their own needs/wants. It's low to no magic based on the shadow chasers campaign in the core rule book. Set around the start of the 2000s.
My current campaign is set in the Star Wars universe, specifically in the Aparo sector near the end of the Tingel Arm of the galaxy, adjacent to the Corporate Sector Authority. The campaign about the adventures a group of bounty hunters who collectively own a medium freighter called "The Dogfish" which has been converted into a small warship, which they use to traverse the galaxy, hunting small time pirates and other threats to the Imperial Peace. It's currently set 46 Coruscant months after the end of the Clones Wars, during the Rise of the Empire, at a time when most of the galaxy approves of the Empire or at least is hopeful that things are going to get better. Many of the Imperial officers and bureaucrats were once members of the Republic apparatus, and the real horrors of COMPNOR, the Imperial Cult, and the Empire's evil isn't entirely obvious to everyone. Luke and Leia are toddlers. Han Solo has just entered the Academy. Cassian Andor is an 11-year-old child soldier in a separatist group. The Alliance doesn't exist. Mon Motha and Bail Organa are still arguing privately over whether arms will be necessary to overthrow Imperial rule and restore democracy.
Our bounty hunters are licensed Imperial Peacekeepers, but not out of any particular love of the empire. They are technically vassals of House Benelux, a major faction in the Bounty Hunter's Guild. Cen Therin, the face of the group, is a human con artist turned legitimate, and an expert speeder driver. Clav Xy is a former Rhodian police sniper and detective, fired for using excessive force interrogating prisoners. Roblox Carvin is a Togorian warrior who left his planet seeking trophies and battle. Taro Ky is Togruta commando - who fought for years alongside Clone Troopers for the Republic in a special recon battalion of volunteers - but who is increasingly disenchanted by the New Order. Slurak is a freed Filvian slave, that the other Hunters bought try to keep the Dogfish running after the Jawa that they used to employ in that capacity died in an explosion.
Typically the hunters take bounties for the Empire on security threats that the local Imperial assets are struggling with, often hired by Imperial Prefects when the failure of local magistrates starts to make them look bad. But if the money is right, the group is not above taking illegal contracts from a group of shadowy figures whom they assume are some sort of Separatist holdouts, and which they now know has some sort of connection to Alderaan. However, they also now know that the Empire knows about at least some of their double dealings, and that the ISB intends to use them to ferret out this group of traitors so their relationship to the Empire is complicated to say the least. They are decorated heroes of the Empire, personally known to Justicars and Prefects as reliable operatives to call upon to fix things, but at the same time they are all the time having to remove ISB tracking devices from their ship and equipment and the Inquisitorious only is keeping them alive in the hope of smoking out bigger fish. Meanwhile the Ubiqtorate and COMPNOR - who don't know about their illegal dealings - think they are above board and laudatory. The hunters themselves don't know whose side they are on, and have been secretly moving their money into the accounts of the Hutts, in case they ever have to turn criminal.
