I always find the demo's tough to play, maybe because it's a new game and I haven't had much time with it. But, I am finding it very difficult to create legitimate goal scoring opportunities. It just seems way too hard right now. And not just against the computer, I play with my roommate 95% of the time.
I know it's supposed to be a sim or whatever, but when a game ends with 4 shots total between both sides, something is wrong. I'm a pretty solid FIFA player as well. I play 11 online and have a very good record (3:1 win to loss ratio). I feel that they need to make some changes that opens the game up a bit more.
I've played pro-evo as well, and it was definitely more fun having games end 4-3 or even 5-4 than ending 1-0 or going to penalties.
edit: I felt that in past (whatever game I was playing, FIFA or PES), if I scored a goal against a friend, it was because I earned that goal. Now, I feel like goals are either scored through some type of fluke, an exploit, or a forced error on the AI's part. However, more often than that, I feel that I am denied a brilliant goal by unbelievable goal keeping.
