Alrighty, so I finished the game at 22 hours (Not really rushing through, just not really dying and getting through areas in one shot). As someone who has played all the other souls games, I really enjoyed this! Honestly, the game was a bit too easy for my first run, as I used a full strength build with a Zweihander but I'm willing to change things up for my second playthrough! The only problem I had was fighting bosses with this weapon and crazy strength made things a joke, as I would dodge through 2 or 3 hits and absolutely drain the bosses health in a few shots.... Maybe I really over leveled as by the time I was at the end, I was level 95. Nonetheless I really liked the story and the characters alongside the gameplay.
The one thing I really dread is the Companion Rank 30 trophy, as you need to basically get 400 medals to get to that rank. You get 1 medal per boss in co-op, so you can see how this is going to be a pain... Hahaha
