I think you're forgetting once again this is not an MMO, but a shared-world shooter. People are building grandiose expectations when truly the ground-breaking features are the adaptation of an FPS to an RPG format. As someone with some familiarity as to the effort each area takes to both visualize, create, and program, I can appreciate the Tower as is. Would additional extras be cool? Yes, but BUNGiE first and foremost is focusing on the core values of Destiny's Desing: Namely good encounters and worthwhile loot. Anything else is secondary.
