All amazing games, but Bloodborne takes the cake, cause the setting was extraordinary and, in my view, the most interesting! The setting makes almost everything in BB 1 step better than other souls games.
Also Nioh... imho, i see why people say nioh is a "souls game" but i truly think its closer to Diablo (lol)! For real, Nioh is different from "souls", it's a mix of Souls and Diablo, and i love the result!
