I was just watching my son play the Neverwinter MMORPG beta. The user interface looks just like other MMORPGs and he could jump right in and start playing.
That’s not because the people at Cryptic Studios lack imagination – it’s because their users already have an expectation of how an MMORPG should look. It would be stupid to risk turning people away by inventing a brand new user experience (UX). Instead, they are using a User Experience Design Pattern that their users recognize.
If smart people (whose livelihoods depend on people liking their applications) use UX design patterns, maybe you should, too? There are well-known UX design patterns for enterprise applications, too. Have a look at the Oracle Design Patterns and Guidelines for some great resources to get started.
