Installed all of the 42 Gb that Shadow of Mordor requires and did a bit of DLC, but didn't find it much fun, so I uninstalled and installed The Incredible Adventures of Van Helsing: Final Cut which takes up 55 Gb and Deus Ex: Mankind Divided which takes up 58 Gb.
Only have 232 Gb available on my SSD, so I got in a dilemma when I decided to watch a few videos of Shadow of Mordor and wanted to reinstall that one, after not really enjoying the swarming fights in Van Helsing. Now I've dedicated myself to playing the whole of The Incredible Adventures of Van Helsing: Final Cut, so I can uninstall it afterwards and make room for Shadow of Mordor. After 25 hours I've started the third game. The Steam page says that the campaign offers 50+ hours, but I hope I don't have to play another 25 hours or more.
For an action RPG it has great voice acting, humor, story and setting, so that's why I keep playing it. Not for the combat or for the loot. I feel indifferent about them, which is odd because I see as those two as the core gameplay aspects of an action RPG. At least the skills are good, but not very good until I had played 10 hours and unlocked the second tier on my Bounty Hunter's skill tree.
