Call of Duty Ghosts is a pretty good game. I enjoyed playing the campaign and also enjoy some online modes, like Infection. I do think the developers could have done a lot better though. Nothing about the game is really a big change; other than female soldiers. One new feature of Ghosts is that you can choose between male and female soldiers.
I think the Call of Duty developers should really take some notes from Battlefield. Battlefield 3 was made in 2011 and is still an excellent game. The graphics are crisp and still look great today.
If you’re looking for a slight change to your Call of Duty gaming, you should go pick up a copy of Ghosts.
