Depends. Do you have an original Xbox?
If so, go out and get the two otogi games- Otogi: Myth of demons, and Otogi: Immortal Warriors.
They were a pair of hack-and-slash games developed for the Xbox by From Software, the same guys who did Demon's/Dark Souls. They're completely unique, and well worth playing. The combat isn't quite as deep as something like Ninja Gaiden or Devil May Cry 3, but the games have more than enough positive qualities to place it along side those games.
Firstly, the combat is far lighter and more aerial based than practically any other hack-and-slash game, meaning you can knock enemies into the air, then keep fighting them above the ground for as long as you can keep the combos going.
Secondly, the environments are destructible. Any man-made object or piece of architecture can be destroyed, usually by sending an enemy flying into it. Nothing feels better than finishing a combo by knocking a demon through a wall, then watching that wall collapse on top of them.
Thirdly, the art direction and production values are absolutely top notch in both games. From Software really managed to capture the 'Japanese fairy tale' vibe they were going for, by combining Japanese mythology with psychedelic visuals and traditional Japanses music. The atmosphere of both games is really quite unlike anything else out there.
The first game offers more in the way of weapon variety and RPG customisation, but the second offers more playable characters (six, I believe) all of whom play diffrently, and overall has a more cohesive narrative. But they're both well worth checking out, and you can get them for cheap online. You need an original Xbox to play them though, as they're not compatible with the 360.
