Playing Middle Earth: Shadow of War.
Its not a bad game, but it doesn't exactly set the world alight. It doesn't really add that much that wasn't in the first game. You still play as the Batman of Middle Earth, I mean, Talion the Ranger who was murdered at the Black Gate and found himself tied to the spirit of Celebrimbor (you know, the Elf who made the Rings). You still have wraith powers that mean you can't die and you still have to find an Orc captain, kill him and move onto the next, occasionally doing missions in between. The only real difference is that you can now recruit those same captains and form your own army to steal forts from Sauron's control. And some Captains might betray you, others might save you at the last second but really there's nothing that pops.
That said, the Shame mechanic introduced in the game offers a sort of perverse curiosity. When you've defeated a Captain, you can usually do one of three things - 1) just kill them by continuing the fight, 2) get information from them, 3) recruit them into your army. At a certain point, you learn to Shame the Orcs, stripping them of several levels. But this comes with a downside, do it enough and you might break their mind or maake them deranged. In the case of the latter, becoming deranged actually boosts their level and makes them harder to fight.
But that's about it.
Look, Shadow of War is a good game to pick up in a sale, but its not a game that I would pay full price for.
(Edit - Also, you're looking at around 90-115gb, so yeah. A whole lot of nothing, really)
