Query: Best of the series, IMHO

I played COD UO after playing COD, COD4, COD2, and the original MOH series. The first mission was very challenging and took a lot of getting used to. Unlike virtually all of the other games in the series, in CODUO, you are supposed to follow Sgt. Moody and do what he tells you to do and move when he says to. There seem to be more enemies in the first level and less health scattered around. Fortunately, the later missions play more like the original game and overall the expansion pack is fun. The game is more similar to MoH-Allied Assault (but has some unique twists of it's own), and has become my favorite game of the series.
