I played Call of Duty: World At War on DS & found it to be pretty good..It would be vastly better if my computer had sound, though...I might even ditch it because of that (I'm also kind of not sure when it saves...)...Some of the mini-game things to do things like disable mines (neat), fire mortar (difficult to judge what's happening at long ranges) & sending morse code (not too hard, kind of neat) were interesting diversions (I guess there are more) from the main action...Mostly though it makes me miss being able to play a real FPS on PC...no offense to this version which I would love to carry around if I actually had a DS...
