Sometimes it seems to me that modern MMOG developers all evolved from the same universal common ancestor of developers, because they can't think outside of their MMOGenetic heritage. If we can have virtually unlimited control over our character's in-game appearance, why not let us customize our animations? Our voices? Our spoken phrases?
Even if we start with an old-school EQ-style multiple-choice option of voices, phrases, and animations, why not give us that? Even better, let us customize them with sliders controls and option switches. Let us connect battle actions with phrases or specific effects of our choosing. When we gain a new skill, give us some personalized, creative input into how the skill is visualized and integrated into our behavioral repertoire.
Let me decide what phrases trigger which animations. Let me have control over my walking and running animation. When I sit, let me pick from a set of styles. When I laugh, let me have some options so that I can flesh out my character.
Sometimes it seems that every new patch to every existing game is about (1) new bosses, (2) new dungeons, (3) new areas, (4) new races, (5) new gear. I don't know that I've ever seen a patch - ever, in any game - that was dedicated to expanding the personality/characterization choices of our avatars. It' s like, after the game comes out, the only thing the development team cares about is satisfying the ravenous end-game or replay (new character) appetite of more hardcore gamers.
One of the most fun experiences I had was with the Champions online character creation interface; it was mind-boggling in its depth. I'd like to see that kind of character creation system, but exponentially increased to include all aspects of my avatar.
