Depends which Fifa. In my opinion, if you want to play Fifa, I would purchase Fifa 12 and try it abit. Start off bad then when you get good at it, Return it and echange it for Fifa 13. I didnt buy Fifa 13 cause i knew the only thing i'll be doing is Black ops Two-ing But yeah Fifa itself is a good game, it can get VERY frustrating at some points but then when you lock away your first few goals you feel great.
I dont know about it. What are the pros and cons of it? Is it worth getting.
Depends.. All in all it's an excellent game to buy if you're a soccer fan! I know some friends that don't even play soccer that enjoy playing it. It depends on the buyer.
I'd suggest to look up some gameplay videos of FIFA 13 and see how you like it. You could possibly rent it from somewhere to make sure you like it first and then think about buying it.
You'll need to play it to get used to the tactical defending and all of the other shit and if you like it from there, you'll enjoy it. It is frustrating though at times
