The gimmick of creating a deep character becomes obvious right at the beginning of the game, where you can choose the race and a 'starsign', which are both just a set of perks, which can create a very unique character. Later on the game lets you completely modify the appearance of a character, enabling you to make your character very unique. In previous Elder Scrolls games, you immediately had to choose the class of character you wish to create. Because it is not clear to first-timers to the Elder Scrolls which style they prefer, Bethesda decided to lets you get accustomed to rougly all types of weapons (melee, ranged and magic) before letting you choose between the many classes. From the Warrior (which only uses melee and heavy armor) to the Mage (which only uses magic) to the Thief (whiich focusses on stealth and ranged combat) and everything in between. If you want to make your character even more unique, you can create your own class. This however requires some knowledge of the Elder Scrolls games. One negative issue is that your race and starsign heavily influence your strenghts and weaknesses, almost forcing you to depend on your previous, possible ill-considered, choice of race and starsign.
Since the Elder Scrolls III: Morrowind combat has not changed much, actually it's basically the same. Ranged combat works well, although the hit chance of your arrows changes with your archery skill, and is not dependent much on how skilled you personally are with the game. Especially if you haven't focussed on archery in the beginning of the game, this can be a bit frustrating, especially since arrows cost money to buy. Luckily you can pick all arrows you missed up from the ground, and loot some arrows which are stuck in your enemy. Melee works well, but can become a bit repetitive. Fighting mostly consists of either hitting, dodging (going back a bit), and hitting again or hitting and blocking. Magic is the most complex fighting style, because you can use multiple spells after each other to optimise damage. This complexity makes it the most fun fighting style, but not as powerful in the beginning of the game since many spells become available only
