Same deal with previous Xtreme Legends expansion based from the Dynasty Warriors series, you can play them separately and standalone with little to no content or have the original disc and integrate the whole experience into one.
This Xtreme Legends is sorely needed as it actually adds a few characters: Tadakatsu Honda, Ina, Yoshimoto Imagawa and Hideyoshi Hashiba. A few new skills and items were added as well. A few quality of life additions and the bonus points system for unlocking alternative stuff is cool but that's really it.
Only bother getting this if you have the original disc as it would feel like a demo disc without the original which can be said for all of the Xtreme Legends variants but this one especially.
