Here are my short impressions after playing the game since 10.30 am yesterday till near enough 1 in the morning... with a short break for Doctor Who and the X Factor in between of course.
Clubs atm is the games saving grace for me, it is actually really fun and the defensive AI hold together well now, you have no idea how happy I was when the other team got in 'that position' for a cutback, went for it and had two, yes TWO of my defenders slam into the other player and clear the ball with no issues, I was over the moon!
The AI on clubs now actually play some really decent football, which I'm pleased about too, I play CAM and it's actually really great.
I then tried out BAP offline and imo they still require too much assistance to do anything decent, without the added humans there it really isn't as fun, I was playing on professional though as World Class offline against the CPU just is not fun imo, online you have the help of other human players on your team making runs etc but offline (even with the run frequency slider up to 90) they just don't move enough.
As for Career Mode, the transfers etc/setup is all great, but the main issue for me is the AI. The same issues from FIFA 11 exist for me, as in the AI have ridiculously high passing accuracy no matter what team they are, I am Man United and Mallorca had a passing accuracy of 92% at the end of the game on professional 6 min halves, which is just ridiculous. The next game I played was against Toulouse and was going the same route before I had enough and switched the CPU passing error up to 100, which had an effect but it wasn't big enough... they were still pretty accurate and all it seemed to do was make the ball bobble more, with the odd misdirected pass here and there.
The CPU in the final third/outside their box make 'precision dribbling' (which I love, the contextual dribbling on clubs is wonderful even with an average player) pointless, as all they done was force me to make a pass or slammed into me and took the ball, they are still way too accurate just outside/inside their box with tackles.
I then tried online against a mate and the usual issues appeared, pace is still a massive problem and on something like Ultimate Team against a bunch of speed demons will show this game in it's worst light.
It also had those WTF moments such as, with Hulk I ran at one of his defenders who dispossessed me easily, then Hulk sort of auto locked onto him and barged into him, taking the ball then proceeded to bounce off his other defender and get through on goal for an easy finish, which if you've ever played 11 online you will know is annoying. I also scored an overhead with Pique using the new modifier from a corner, which by the way are still WAYYY to easy to get a free chance at goal from, although headers do seem to be less accurate which is a great, great thing.
Players do auto tackle as well, they may not do an animation but 9 times out of 10 it seems easier to just barge into them and take the ball than time a tackle, as people online don't have the insane reflexes the CPU seems to, so defending wasn't really difficult in the 10 games I played... whenever he came at me with Ronaldo I just used contain. (The only time contain will be helpful will be against those insanely quick players, as you just mirror them perfectly and all they can do is pass or run into you... it's actually ridiculous)
So as far as the game goes for me, Clubs is good enough to warrant a purchase but I fear that when all the VPs get highly rated it will just fall apart, hopefully I'm wrong.
Offline is just ruined by the CPU AI for me, I'm still hoping that someone will come up with a great slider set up that changes the game, but atm I just don't see it. To get any enjoyment I'd have to play on semi pro which is just too easy... where as with professional it isn't that it's hard, I just don't think the way the CPU can anticipate your tackles with turning perfectly at the right time, their highly ridiculous passing accuracy or insane need to get out to the wing to swing a ball in fun. I'll just never find playing against this AI fun, unless someone can change the way they work with the sliders...
... Clubs is still fun tho.
