Query: Disappointing

Very disappointing, specially coming from the guys at EA who created the Medal of Honor series. The original Battlefield was original and fun to play, but very low quality graphics and play control. Battlefield Vietnam is no better, just different weapons and maps, they may have updated the engine a bit, but the game runs slow and is prone to bugs. I bought Battlefield Vietnam hoping that it would be much better then the original, but I was disappointed. There is another one coming out, but I think I will wait awhile before buying that one.
