If you saw last years line up of games, you would have noticed a LOT of sequels came out. Far Cry 2, Gears of War 2, GTA IV, Call of Duty 5, Fallout 3... the list seemed endless. Some were good, some only average. Some may have tarnished the reputation of their series beyond repair. It's just the risk developers take when they choose to continue a tried-but-true game type.
