I'm not being defensive mate I'm just stating facts.
Let's be honest PES has been poor since PES 5/6. Although PES 2011 is a massive improvement it's still lacking in so many areas. It's almost like the PES we should have been given 2 or 3 years ago.
Animations are terrible, the passing is too assisted, the player movements are clunky, the shooting is too assisted, keepers are awful, AI is piss poor... I could continue...
What the hell? Where does that come from? Have you even played the full version of PES 2011? Animations are pretty decent in PES 2011, they are fluid and seem very realistic. Sure they aren't as many and as varied as in Fifa 11 but it really plays a smooth and responsive game.
The player-movements aren't clunky, it just happens that they have some inertia like real players have, in Fifa 10/11 they are too easy to move around and change direction, as there inertia is missing. In comparison PES 2011 might feel clunky but it's really not, it's that Fifa misses something.
The passing in PES 2011 is similar to Fifa's semi-assissted control with power-assistance off, it feels just right.
The fascinating thing is that short passes are more assisted than longer passes and if you want to go manual you can press L2 and it's manual.
The shooting is indeed assisted but not too assisted, you can direct shots high or low, right or left, volley, lob... it could though be a bit more free.
Keepers are actually very good, they are reliable, the only problem with them is that they need more animations to make them look better while making their saves and parries.
AI is very good, the team-AI is way better than in Fifa 11, realistic and varied. The individual's AI is not as aware as in Fifa but in the full game of PES 2011 it's way better than in the demo. The opponent's CPU-AI in attack at top-player is really challenging, much better than in the demo.
PES 2011 is imho the best PES, better than even my beloved PES 5 and definitely a credible alternative to Fifa 11.
