Just get it for PC? I have 150+ hours into each of '12, '13, and '14 on PC, mostly playing career mode. Online is non-existent due to the small player base, but I'm not particularly interested in it anyway. Visually the PC version is superior to all others due to AA and the better framerate. If you are only interested in playing online by all means get a console, but the single player PC game is objectively better than the rest.
physics way different. feels more intuitive. stamina is very important. i just played a match with a dude who mashed sprint. he binked one on me in the 40th minute but i had every ball toward the end because i don't play like a maniac. unfortunately, because i just started playing fifa a month ago, i was like 0-10 on shots. I felt like at least 3 of those were goals in 14 and to be fair, I have hit the bar three times in the two matches i've played (2-0 loss and 1-0 loss) GKs are better for sure. Far posting has been nerfed for sure. Actually just scored with the finesse shot which was really rare in 14 for me.
I like it so far. I think it's a definite improvement. I'm just really lousy at it.
