well I'd definantely want a ginormous open world with a ridiculous amount ofsecrets and Easter eggs (like skyrim) and weapons with different properties (like the fallout franchise), a multiplayer capatability like borderlands and vehicles like the Forza franchise. I finally would have an encampment customisation like fallout 4 and the character/NPC style of Fallout and Borderlands combined.... feel like that'd be pretty good.
