this is a fighting game right?
This is a brawler, which is like a fighter, but closer to Dynasty Warriors sorta deal. Anarchy Reigns has a pretty advanced combat system (nowhere near a fighter, but way more depth than a Koei title) and the characters are pretty diverse.
You have to realize that this game was NEVER intended to be $30 dollars, Sega just made a stupid move and delayed it. In this time the Japanese version did pretty poor (partly due to marketing, partly do to flaws in gameplay / story), so they instead put forth no effort in the US / EU and merely dropped the MSRP to help sell it. Having paid $90 dollars for it, I can't say it's worth it, but I can say it's worth $30.
