I played many games at Origins!
I think this is the whole list: Paris Connection, Millennium Blades, The Networks, Pandemic: Reign of Cthulhu, Watson & Holmes, Century: Spice Road, Troyes, Favor of the Pharaoh, Colony, Aeon's End, Vast: The Crystal Cavern, The Voyages of Marco Polo, Among the Stars, Near and Far, HMS Dolores, Dark Moon, Blood Rage and Glux. Also got to demo Codenames Duet at their booth.
I think Near and Far was my favorite. It is a nice resource gathering and map exploring game with bespoke quest for every potential location on the map you could quest at. The game loop of assembling a party, leaving town, establishing some camps, and maybe hitting a quest before heading back home to spend your loot was very satisfying. It helps that it has super gorgeous components and some really fun writing. There's a campaign mode and a bunch of different maps you can play so it seems like you can get a lot of mileage out of it without just doing the same quests over and over.
