Mordor is a lot of fun, and has an innovative system called nemesis, which means each game played will have it's own hierarchy of orcs that constantly updates based on what you do, and will be different fur every playthrough. It can get a little "same old same old" but no where near as much as Destiny. It's really subtle, needs to be played to be understood. Combat similarities were made to batman. DAI is massive, if you've played DA origins and liked that you'll probably like this. Open world like skyrim, but not a sand box.
