Dungeon Siege Legendary Pack is a modification which allows playing the original Dungeon Siege and its expansion pack, Legends of Aranna using the enhanced Dungeon Siege 2 engine. The mod requires that the original games are installed prior to setup as original assets and maps have to be converted in order for them to be playable in Dungeon Siege 2. Setup will abort if the original games aren't detected prior to installation. About 1Gb of free HDD space will be required to install all 4 maps.

I loved first Dungeon Siege and really enjoyed second game, so when I heard of DS II Legendary Mod I took it for granted that it's 'must have' mod. And I was not disappointed.
