There’s a pretty great thread about this over here, but one thing I find will make me immediately perk up and take notice is a base that I can build up over the course of the game. Stuff like the assassin HQ you can build up in pretty much all the Assassin’s Creed games, or the base in The Division, or even the dorm room in Bully that you can kind of kit out as you play. I love to see that kind of thing. Even the new Metal Gear Survive game, which doesn’t really interest me all that much, looks like it may have this as an element.
