I don't think you understand how difficult developing a legit game is. Have you ever developed a game, I don't think so. Developing a game is the most frustrating thing a person can go through besides being unable to get a boner. There are so many times during the developing process where you want to do something, but you just can't make it do what you are thinking. I've made small games before, and it took me slightly over 8 months to make one. Just because of trouble making it do what I want it to do. Sometimes you do exactly what you think will make it work, but it just doesn't turn out right. EA Sports develops games so quickly because they have thousands of people working on each game. My bet is JibLife has tried to do some stuff, but have just not been able to do exactly what they have in their minds. And, JibLife has a smaller group of programmers than EA does.
Point is, developing a game is very difficult and frustrating. It's not just typey typey BOOM game. It is so much trial and error to make it do what you want it to do. And I've been developing with easy languages like Java, and that's for a tiny game and it still takes me forever.
