Keeping with its hack-n-slash roots,
Legion features a straight-forward control scheme. As easy as the setup is to learn, it is not the most responsive thing in the world. Sword swings are slow, making it hard to time strokes, which is particularly frustrating since it is a major play mechanic. At the end of each of your swings, a faint (and some could argue barely noticeable) spark appears at the end of your sword. Pressing X in time with this spark produces a combo attack, which - if done correctly - can have nasty results. However, since the controls are sluggish in their response, getting this combo off is hard.
Legion is especially unforgiving for button-mashers. Simply mashing the attack button for a flurry of quick jabs is not possible since the game has to run through the entire (slow) animation until you are able to attack again.
To be honest with you, Legion was a hard game for me to review. For the most part, the game seems to slip between good and average. There were times when I would play it and have fun, yet there were also times that I couldn't wait to turn it off. Despite some obvious flaws, the game can be fun for players who are willing to push through the muck and get to the core of the game.
