Dynasty Warrior games are great, some must be considered instant classics. Though Koei does release some Dynasty Warrior games that are clearly beta tests for the next installment, so I suggest seeking out DW fans on which ones to buy. It can a Final Frontier / Wrath of Khan difference. My top suggestions are DW4 and DW7.
It surprises me to that people hate the Dynasty Warrior games, but reviewers often gives these games low sources and idiots that think reviewers are as god like as Jim pretends to be tend to repeat this belief blindly. I have actually been insulted for buying a DW game at a gaming store, by the person working there. I asked him why he didn't like DW games, and he really couldn't give me an explanation, it was just that he thought he was expected to look down on DW games.
Everyone knows what a multiplayer hack and slash is, imagine that on a battlefield with millions of soldiers, leveling up, and elephant riding. You know by now if that's something you'll like, DW is not going to disappoint.
By the way, it turns out "Red Hare" was his horse.
