I liked the original but found it a bit too punishing/affected by RNG. But I LOVE the sequel - they smoothed out the worst rough edges and made things more predictable. For example, no more hit% for attacks - now attacks hit unless enemies have a Dodge token, which gives then 50% miss chance and is expended after one attack against them. And of course the roguelike structure is a great fit. I feel like this is the perfected version of Darkest Dungeon mechanics - you will suffer, odds are overwhelming, but you have a lot of options to mitigate or occasionally even benefit from bad status effects, and combat is much more predictable.
I think it’s a great game and I’m interested in the DLC.
