Gears of War 3

Gears of War 3 is the concluding part to the trilogy. Originally with an April 6, 2011 release date, it was moved to September 20, 2011 to anchor Microsoft Studios' holiday portfolio for the Xbox 360.
Started Gears of War 3 yesterday and I’m really liking it. Is it worth going back and playing the first two? Also I feel like I’m missing out by playing alone... is split screen way better?
