I own WOTR, Chivalry (And the expansion), and of course Mount and blade.
WOTR: I thought WOTR was a bit clunky in terms of game play. The melee was slower, yet felt harder to block. The horse controls were also hard to use compared to Mount and Blade. I still thought it was an alright game though. 5/10
Chivalry: Love this game. The dismemberment, the first person, the swings and hits which felt like they had weight to it. All of this made it feel like a great game. I would say it was more of a fun game to dismember and maim people than it was to actually duel and be competitive. But that's what made it fun. Pure medieval combat. 8/10
Mount and Blade: This is a faster game than the other ones. It is competitive, has fast game play, and it is filled with crusty veterans and no lives. These three things make this game a great, addictive experience which will satisfy only the elite master race for many years to come. 10/10 Would pledge my life to.
