The game has one of the strongest roaster of main bosses in the series. The bosses are challenging but very well balanced. Personally I felt the game is a bit easier as compared to the others in the series and that is because the game rewards the players who figure out and get used to the patterns and the mechanics the game has to offer.
The game takes good amount of influence from Bloodborne, be it the faster combat or spooky areas with somewhat spooky enemies or lot of howling and shouting here and there etc. The game also has some really heart warming throwbacks to the OG Dark Souls and I loved how they picked up few interesting mechanics from DS2 as well.
For me a really important aspect I look forward to in a souls game is the exploration bit. Going through the world, exploring secrets, finding shortcuts etc. This aspect in DS3 was somewhat weaker for me. Now there are secrets to uncover and shortcuts to find but the world felt a bit bland in terms of variety and it looks less vibrant. Having said that, I do understand that world is designed keeping in mind the context of the story and definitely the overall visual storytelling is very strong. The themes of decay and stagnation and very well depicted.
An amazing game overall.
PS: The DLCs are truly epic with some really memorable boss encounters. Ringed city is peak Dark Souls.
