If you are a die hard RTS fan looking for a new challenge, Infested Planet's mutated hordes might be just what you are looking for. Everyone else be wary. Infested Planet is easy to pick up and play, but its alien army wants nothing more than to tear you apart.
Escape Plan has come to the PlayStation 4, but it fails to make the transition cleanly. The puzzles are dull and the controls are ill fitted to the new system. I wouldn't recommend playing Escape Plan, but if you absolutely must make sure it's the Vita version.
In the end Ghosts is indeed another Call of Duty game, but one of the weaker releases over the past few years. The new multiplayer modes are exciting, but they are bogged down by the low quality maps. If you just need a game to scratch your FPS itch, Ghosts will tide you over till another Call of Duty comes out, but if you are looking for a shooter that is surprising and profound, you are better off passing on Ghosts.
