I think that this would be nice. The more tools that are put into players' hands to play with the more creativity can be spawned which means fan-made media such as sharing screencaps, stories, and videos on YouTube. It makes it immersible for players who like to roleplay or just have fun and it is a free engine of creativity and marketing for SE outside even of contests. A little programming up front can go a long way! The proposed "vanity slots" (skins essentially) could really help those who want to mechanically show off their accomplishments as well as for roleplayers who may want/need a look or mechanical benefit to something that looks different. Think about your favorite Minecraft videos (such as the YogsCast) for example. The more that is put in the players' hands, the more fun and sharing can come from it.
