I thought I'd mention this if anyone hasn't heard of it before. FIFA World is EA's free version of FIFA for the PC. It doesn't have all the modes as it only includes Ultimate Team and league team vs league team however its quite good for a free game.
EA Sports FIFA World
I got an email from them about this. Could be interesting.
I forgot to mention its PC only. I mainly play FIFA online so I'm tossing up whether I need to buy FIFA 15 as its a free game and gives me what I need. Unfortunately it doesn't allow for Creation Centre teams but I guess they only want to allow so much for free. If anyone has it you're more than welcome to add me as a friend on Origin, JasonLTee10.
