UI Updates
As the direct interface between players and their game, the User interface can break a MMO, or any other kind of computer software for that matter.
Since the game was first released, many changes have been made to the SWTOR interface and, at least according to the Bioware staff, it is now in its optimal form pending release of the game. Many possible layouts were looked at, and a team of players and developers have worked together to decide on the best looking and most useful of these.
Although originally Bioware had elected for a more artistic feel, thankfully over time this changed to designing the interface solely around usability. As such, most of the unnecessary fluff has been stripped away and we are left with a streamlined, and thankfully minimalist UI.
Many players with low-res screens will be well aware of the problems that come with an Interface with a lot of useless additions. As almost all of the windows are necessary, having them large takes up a lot of room on the screen, stripping down the visible area of the game, which when it consists of SWTOR’s graphics, is not something anybody wants.
As of yet, no details have been released as to how customizable it should be, but we are all hoping for it to be as adaptable as possible. In many games, such as Galaxies, windows on the screen could be moved, removed, resized and otherwise adapted to each players’ individual wants. This made for happy campers, as it could be organized to fit different size screens and players which made the game in general far more accessible.
Although there has been no word on whether Bioware plans to follow suit in this regard, we do all hope to see options available which, even if left alone for most players, will help out those who would otherwise struggle to participate.
