Salieron los primeros reviews, en Destructoid (5/10), Polygon (6.5) y Giant Bomb(3/5 estrellas) le dieron palo.

Giant Bomb
The basic core of fast-action multiplayer shooting is largely intact on all platforms, but Call of Duty: Ghosts tries new things that don't make the game better while omitting features and modes that players have come to expect from the franchise.
Polygon
But Call of Duty: Ghosts demonstrates an unwillingness to change much and presents a real shortage of new ideas. Ghosts is a step backwards from 2012's Black Ops 2 — and the weakest game in the series since 2009's Modern Warfare 2.
Destructoid

Call of Duty may have picked up a reputation as one of the laziest, most callously developed cash cows in the business, but I've always believed that reputation was undeserved. Call of Duty: Ghosts, however, with its slapdash campaign and unambitious multiplayer, contains enough factory-standard cynicism to earn itself plenty of scorn. Nothing Ghosts does is especially bad, but nothing Ghosts does is worth paying any attention to. It exists to exist, a stopgap bit of filler spat out as the industry transitions from one generation of consoles to another.
Contrary to the old saying, you can teach an old dog new tricks. Black Ops II demonstrated that with style. Ghosts, however, is a dog that simply doesn't want to change. It knows what it is, and sticks with it. It would be a respectable endeavor, if it didn't lead to such an underwhelming and predictable little product. What a sleepy, sleepy dog.
No me esperaba un declive tan grande mas allá de la gente que no le guste los COD, Modern Warfare 3 era un buen juego con una campaña muy bien orquestada.
Se ve que las partidas de staff a Respawn lo golpeo duro a IW.
