Brrr... I also liked fighting outside much more than in dark scary caves.. Usually I tryed to do quest in caves during the day (real time), they were less scarier then

But to stay on topic, RAI is definatly the one thing I look forward the most, it seems very wellworked. In connection to that I also look forward the "life" of the game, mostly city-life, were I would look at people wander about doing their chores and myself taking part in everyday life.
As a second connection to RAI I'm looking forward the quests, especialy the non-main quests, I want to see how immersive they are, how personal they become and how well they are build. I hope to take part in puzzle-like quests like solving a mysterious murder for the local guardpost... That would be really cool.
