SO a quick sum up from me on FIFA 13 so far. Before I go on though, I am not an ultimate team player so I don't really have anything to say about it in 13.
I am really enjoying the games presentation, has a much more Sky Sports feel to it than before, seems like with every iteration it get more and more TV like. Little touches like the scores being read out as you tinker round the menu's and the cup draws being read out as you anxiously wait to hear who you have been drawn against add to the immersion somewhat.
This translates into the game, its definitely feels more unpredictable to play, theres more loose balls, interceptions, deflections and so on. And many many more runs from players, user and AI sides both seem to ooze intelligence with runs and its a joy to watch and play. Even if your defence does get ripped apart sometimes

. And again the broadcast aspect shows itself in game as well, much more TV like angles, more activity around the stadium with cameras, officials, even the managers patrolling the technical areas, improved player likenesses and the commentary is very good indeed.
In fact I think commentary is one thing that has come on leaps and bounds, used to be an instant "turn it off" for me before even hearing it but now its a mainstay in my experiance. It flows a lot better than it used to and they talk about relevant things. The additions of Geoff Shreeves with his touchline reporting on injuries is superb and actually helps you gauge what might need to be done, whilst the option to select other games to receive updates from is cool, and brilliantly delivered by the ever enthusiastic Alan McInally.
Career mode is where I spend most of my time, and the improvements here are hugely welcome. Being able to play in Europe from the first season is something I hadn't missed or even noticed barely (playing as Newcastle it would have been rare anyway) but now its there I couldn't go back to not having it. They do well to skirt licensing issues by drawing the 2 tournaments (named Champions Cup and Euro League) at random. Addition of international management within career is massive as well, finally the nations have a place in FIFA, and not just make up the numbers and better still, you can still manage your club as well, so I can manage Newcastle AND England which is very cool.. World Cup and European Championships both represented with full qualifying and tournaments plus friendlies. Its also great to choose your own squad as well. Finally can pick MY England squad

. For the English players as well the League Cup is finally licensed and is now in game as the Capital One Cup.
Everything else is more tweaked than revamped, first touch control is superb now, the impact engine is very detailed and much much improved over last year, makes the games looking incredibly realistic and superb. Transfers feel a lot more involving and it feels much nicer to close a deal, you also have more options like counter offers, loan with option to buy and even player swaps. You can also now change club mid season through the managers office, should another vacancy arise that you wish to go for. No more waiting to the end of the season to see who wants you.
My impressions therefore are favourable, and having only bought it a handful of days ago, I cannot put it down. 10/10, best sports game ever.
