I'm on an LG OLED 4k, and I can whole-heartedly recommend it. It's difficult to go back to a normal TV after that..
Anyhow, I also finished Assassin's Creed: Origins. Took me 92 hours and I even killed all the war elephants and won all the arena events. The only thing I intentionally left were the chariot races because I didn't like them. At all. Very good game all in all though. So much to see, so much to do. I also thought the side-quests were generally excellent and tied in with the main quest quite elegantly.
I had no problem blocking so for me it was working as intended. You can't just hold the block button or the enemies will start hitting you with block breaking moves (yes, even low level enemies). Dodge, evade and block, not just block.
I also finally finished a playthrough of Rise of the Tomb Raider that I started before Christmas. Funny thing is that I had actually stopped playing that game with 98% done and basically only the end battle left, without knowing it. It took me longer to get my bearings in that game again than it took me to 100% it.
I'm guessing next up on the list is an old playthrough of Shadow of Mordor that I have left hanging a while ago. It's just that I had my fun with the fighting system in that game and after that stopped being fun.. well, it feels like a drag to actually finish the story. We'll see.
