That is not bias. I have 205 hours on the game which includes me playing all mods and aspects of the game. If you haven't found any glitches or graphical errors in the game, I doubt you are playing the Warband I am.
Physics: Arrows do not come down. They fly like a bullet. Arch is hardly visible. Horses are glitchy and hard to use, and you/they can go flying when killed. There's more, just look around.
Combat: I have mastered blocking, chamber blocking, etc., in the game. In cRPG, it's easy to be 'good' by becoming an Agility pure and spamming all in your sight. You can get as many as 5 kills a game doing that.
Jumping: I'm sorry, but have you even played the game? Jumping is bad, just bad. Try jumping off a bridge - you stay in the same position the entire flight and then you land on your feet or go into some ragdoll position.
Objects being glitchy: Play the game, come on! You get stuck easily, you can pass through some objects but others are solid..
Engine = Graphics + Physics: Described above.
Please list some of the games you have tried, I am interested. I haven't found many games of the genre.
