I had more modest aims in mind when I posted that - I'm not really much of a role-player, but I do miss the immersion of earlier Civ games. It feels lacking in this aspect to me - maybe it's just that I've played the game 2000+ hours but even when the game was released it didn't have that epic "Civilization" feeling of feeling like it's the actual world you're playing.
Some things I would like for immersion would be less linear mechanics (for example, monument, amphitheater, opera house might as well be called culturebuilding1, culturebuilding2 and culturebuilding3, and until BNW is released, no mechanics change through the eras), less cartoony map graphics with smaller scale (Civ 5's maps feel quite dead), more need for city specialization, and added minor flavor enhancers (ie, random events that don't kill your game, something like the slider so there are trade-offs, animated tiles, etc.). I also hope the next iteration is a little darker too, with revolts, slavery, etc.
