The game that was shown to us lacked a lot of things that apparently are in the development version but not in what was shown to us. The weather system was one of them, which they claim is a dynamic system that is completely controllable by the designer to allow changing the weather based on the situation and emotions they want to player to undergo. Other things that were not in were NPCs, monsters, a range of weapons, spells and a working combat system. All of these things will be in the first chapter, though. What was already in was that there is no loading time in a chapter; the only loading time you will have in Arcania is when you start the game and when you go to a new chapter. Inside the chapter there are absolutely no loading times, not even when entering buildings or dungeons.
