Dead Space 3 Is Less Than Aliens: Colonial Marines ?

I just find it weird that Dead Space 3, which has had good reviews across the board has been on sale for $40 two days in a row for limited time offers, but Aliens: Colonial Marines hasn't dropped in price at all ,even though it has some of the worst reviews from all outlets except EGM.

Add to the strange cake that Brandon Justice, who gave the good score of Aliens: Colonial Marines, just left EGM. He kind of went out like an *ss. He made EGM look bad and then left, that's a solid jerk move.
