CoD Black ops 2 or CoD Ghosts ?

Ghosts hasn't come out yet... there is no way to know.

well black ops 2 will be cheaper and has zombies

not much is known about cod ghosts or its special modes so its best to wait

Wait for Ghosts.

Call of Duty Ghosts

If you want one with better graphics, then Ghosts. If you want one with LOTS of enjoyable multiplayer maps, DLCs and zombies, then get Black Ops 2.

I wouldn't recommend Blops 2.

And I don't know about Ghosts.

I'd personally get neither, but if you really want one, then hold off until Ghosts.

COD - Ghosts will be a better choice GO FOR IT..

Ghosts. Black ops2 should be renamed crap ops2 . But if you don't want to wait mw3

What about an actual good fps?

Like doom, quake, unreal tournament, xonotic, warsow, team fortress, fortress forever, serious sam, painkiller, counter strike, killing floor, left4dead, portal and half life!

Neither, COD is garbage.
