I played BLOPs and initailly found the game campaign to be poor graphically with a not too bad story and multiplayer. Then i tried it in 3D. It changed the game drastically. It became the best campaign id ever played and added a new dimension to the multiplayer, although it didnt really make it any easier...
Before trying the 3D id say the MW1 and 2 were better games than BLOPS.
The 3D element turned this game from my worst to my favourate in a instant.
I also think the multiplayer maps in the 1st BLOPS are the best than in any of the series.
BLOPS 2, was therefore hot on my list of games. I can only say stick to the 1st, do not buy this thinking it will be better than the 1st or an improvement.
The 3D is ok, but no where near as good as the 1st BLOPS.
The campaign is tough to follow at times and i switched off from the story and just skipped forward to action. The action/missions are o.k in parts but its nothing that you havent seen already in a COD.
The multiplayer is frustrating at best and no patch on the 1st. I dont know why but it is alot harder to get a kill streak going on this game and the maps are no way as good as the 1st.
Some of the guns are class, but as another reviewer said, they do sound the same and its hardly a reason to stick it on and then find yourself shouting at the screen because youve just been jipped for the 100th time by someone you shot 10 times thats just turned around and killed you with one bullet...
