Beside a very good story/plot, interesting characters and the already shown stunning visuals, there should be some kind of Radiant AI system, like the one of Oblivion, which gives the world's npc different tasks for each simulated day -> ~schedules.
But the biggest wish for me is, that it should be released when it's really done . I don't want to see a second Gothic3 desaster.

maybe they kept a few bugs at launch to make piracy harder <img src="/ubbthreads/images/graemlins/ROFL.gif" alt="" />

A common theme in your posts is a big environment with lots of variation - easier said than done of course <img src="/ubbthreads/images/graemlins/winkwink.gif" alt="" /> If you'd have to chose between:
Lots of levels with each level being very different, connected through a map a.k.a. Baldur's Gate or Fallout
One big seamless world with more or less similar graphics throughout the map a.k.a. Oblivion
Less detailed graphics in one big seamless world but with lots of variation a.k.a. World of Warcraft
Which would it be ?

To me it would be a world like oblivion too
but maybe more different towns (maybe the world of oblivion was too much a human controlled world)
and especially more different caves (and as i already said in another post, the planes of oblivion were too similar for me)
It made me wonder what the hell people have against daylight or light environments it would be nice if we could actually have more stuff to do in that big world instead of always finding caves or ruins (im not saying there shouldnt be any, but id choose 10 different caves over 100 similar ones any day)

this just made me realize i want to eat the cake and have it too
so...another option <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
More detailed graphics in a big world with lots of variation a.k.a. Larians next RPG !

btw wich one would you choose lar ?

There is no spoon !
