They didn't get the bad scores because of expectations. They met my expectations exactly.
What did Factor 5 screw up in RS 3? On foot. The engine that managed the third person ground pounding would have been deemed cumbersome on a late N64 game.
In every Lair preview the presence of a lot of time on foot movement was noted. Given Factor 5's recent history of really messing up a game by putting a lot of stuff on foot, I expected them to do the same here. After reading the reviews that's exactly what they did.
On top of that, the reviewers claimed the SIXAXIS did not help the gameplay, and in some cases made it less intuitive and fun. Shoehorned, is how I'd sum it up in a word.
The game got a bad review for bad controls. This time, however, Factor 5 managed to break the airborne stuff (to a lesser extent) too.
It should be noted that PLAY magazine gave the game a 9, but they also have a prodcut called "PLAY Magazine Presents: Girls of Gaming," that is listed early on their "about us." Take that how you will.
GamePro gave it a 3.75/5 (75%).
"To be fair, the motion sensing is pretty accurate but requiring you to constantly move your hands around while fiddling with buttons over the course of a fairly long game is asking too much." They also used the dreaded "g-word."
