Dynasty Wars is a port of Capcom's horse-based arcade brawler based on the Romance of the Three Kingdoms mythology. Its unique combat features mounted characters, left-right attack buttons, charge attacks, screen-clearing magic, and tons of simultaneous enemies. It also has several voiced cutscenes.
This is one of the only games Capcom released for the PC Engine, although it was actually developed and published by NEC.
The characters seen in this game are also playable in the follow-up arcade title, Warriors of Fate.
Tenchi wo Kurau is a solid, atypical brawler from Capcom. I really enjoy the Renegade-style left-right attack setup, and the charge attacks are really fun to use. Plus, the enemy waves are huge making the gameplay legitimately hectic. Unfortunately, the downside of this is that the sprites are super tiny. The music's good but not great.
