I was just wondering if anyone knows of any really good war games for the ps2?

Have you ever noticed that games that are for playstation 2 and for other systems such as x-box 360 and playstation 3, the playstation 2 always has the weaker games. for example the new game call of duty world at war the graphics and the number of glitches are alot more then other systems and there is no multy player... why they do this i dont know but they should stop because me and many others are sick of spending our money on these games that suck!!!!!!!!
