Dark Messiah of Might and Magic

One of the most AWESOME games I played. It compares to Skyrim, though it's linear, rather than open-world. It's on the source engine, so that means a lot to me. The combat is awesome. The graphics are awesome, the level design is too. The music, the voices, the characters, the story, it's all beyond awesome. You should definitely try it. Too bad it doesn't have a sequel, but the studio that developed it has been taken by Bethesda's parent company, so I could imagine they had a hand in Skyrim and other games.
