Fighters are best at combat, but have no real spell casting capability. Magicians and Clerics are magic users, but have very weak combat skills. You can also choose between male and female characters, although there are reportedly no functional differences between the two. Instead they level by applying the exp points to one of six statistics that make up your character. We'll have more on how these all work together, and which ones are important to which classes in the coming preview.
Players can buy additional items, and certain items wear out and break with repeated use.
You can take these items to a repair shop, or attempt to repair them yourself, possibly creating a career for yourself in the process. At its basics, it allows you to set up and maintain your own little village or colony once you reach a certain level. That level is currently 30, and you must complete a quest to obtain the ability. Once you have your colony ability, you can then build structures and even train troops to defend your territory. I'm am very interested to see how this plays out in terms of game balancing and overall gameplay value, so stay tuned.
