It was cool to finally playthrough the whole game, since I didn't manage to finish it back when it was released. If you played the original MOH games, you'll be surprised how well the overall "feel" of the previous games carries over to this title.
While it starts off fun enough, the difficulty spikes hard and some missions become extremely frustrating. I'd really recommend toning down the difficulty towards the second half of the game.

Despite the flaws it's still an impressive game, some of the set pieces are very well done from a technical side of things. The expansions are decent, though Spearhead is the one I enjoyed the most. Breakthrough is alright, but got boring quick, since it felt like playing through a bunch of cut levels from the main game.

If you enjoyed the PS1 Medal of Honor games, it's still worth checking out, since it has a certain charm to it all.
