C&C 4 was the greatest RTS game ever created. I remember when I was trying to figure out exactly how this new model worked and lost interest, but after a few days I was inspired and realized the genious of this game. It was fantastic! Greatest game ever! The problem in my experience was most players did not get over the hurdle of understanding like I almost didn't. Thankfully I stuck with it after a few days. Never had that much fun before in a computer game.
