Warriors Orochi 4 will not turn a non-believer into a believer. If you are already uninterested in the Warriors franchise, or musou games in general, Warriors Orochi 4 isn't going to change your mind. Yet, I imagine that for most fans, they're merely looking for more of the same. Despite being formulaic and repetitive, you know what you're getting with a Warriors game. And if that's your thing, you'll no doubt have some fun with Warriors Orochi 4.
I do love Valkyria Chronicles 4 for many reasons. Its characters are more endearing than any I had encountered in the series thus far and its systems and mechanics are still as engaging as ever. However, there is still plenty going against even its most positive attributes.
Like most games, how good of a time you have with Haunted Dungeons: Hyakki Castle will ultimately depend on what you bring to the experience yourself. If you're hoping for the next great dungeon crawler, then you most likely will be disappointed.
