Arcania - Impressions @ GameSpot, IGN

GameSpot had some hands-on time with Arcania at E3:

The island of Argaan--one of three on which the game is set--is divided up into six regions that will become accessible for you to explore as you progress through the game and unlock them. The coastal region that we were walking around in had some interesting spots to explore, including marshlands with a green mist hanging over them and lots of huge trees, one of which was hollow and had been turned into a neat-looking building of some kind. We also found our way down into a maze of underground tunnels, but we backed out of them before we got lost because they hadn't been textured yet and there really wasn't much to see.

...and there is a gallery of screens here.

And over to IGN:

Magic will also be at your disposal, so you can do things like wing fireballs at foes instead of trying to slice them with your sword. To go about powering up, you'll have a skill tree that follows a few branches and allows for differing play styles, which is meant to be more convenient than the trainer system found in something like Gothic 3. There will be guilds you can join up with though, some related to combat and some to non-combat disciplines, that'll give you access to more abilities and options for play.
