I actually had some fun with Dungeon Siege today. And I'm close to 8 hours total play time.

I got to the end of the snowy overworld and reached the next objective: Ice Caves. Unlike some other dungeons, this place was fairly well designed. Also had to use a little caution with the enemies (mostly spiders, mages, and ice monsters), as they were often attacking in very large groups. They sometimes would appear out of nowhere to surprise you, too.

I'm not actually finished with the caves yet, but I think I'm pretty close to the end by now.
