The original Dungeon Siege was released way back in 2002, with Dungeon Siege II following in 2005. With no sign of a sequel for many years and the original creators, Gas Powered Games, busy developing a number of other titles it didn't seem like a third in the series would ever eventuate. Having been a fan of the series since the original was announced, this was almost as sad to me as the long delay between Diablo II and III.
But at long last Dungeon Siege III (DS3) was unleashed upon the world this year. It wasn't developed by Gas Powered Games, it wasn't going to be as party-based as the previous two titles, the skill system wasn't going to be freeform anymore and it wasn't going to be a PC exclusive - perhaps the most egregious of all the changes, in some circles. Obsidian Entertainment have brought a lot of changes to the formula for their version of Dungeon Siege.
Fortunately, some things never change.
