Why buy either when you can get DKC:TF?

BLOPS2. No contest. Just sold my copy of Ghosts to get BLOPS2 back.

Wii U players are pretty weak. Get Black Ops 2 and kick ass online. Doesn't matter which one, really. Which ever is the cheapest.

BLOPS2, my cousin has Ghosts on PS3 and it's awful. It looks bad (similar to MW3), it's respawns are horrendous, is a complete mess, the dog is just a scorestreak, and it's pretty much the same game as usual. Plus, you will probably find more people online in BLOPS2...

my brother is a COD fan and bought both on release day but lately I have seen him playing BO2 when one would think he should be playing ghosts, so maybe there is something better about BO2

Well, the story is pretty lolz and I doubt many people play online... Its like a ghosttown in the PC version so i doubt anyone is there on the wiiU version

Black Ops 2.

Wait for Smash.

I loved Blops, but I like Ghosts much more than Blops2

sometimes the respawn blows on ghosts, but I chalk it up to not being fast enough more often than just bad spawn.  I did not like the maps in blops2 near as much as blops, and ghosts just felt better.  also, I like the leveling system in ghosts better.  in blops you could earn points and buy what you wanted, in blops2 you had to lvl to get the shit you wanted and had no control.  in ghosts, it's kinda back to earning points and buying what you want again...in a way

None pick up Pikmin 3 if you haven't the game already! I tried it the other day and was incredible, my first time playing the franchise though.
