The 1st thing to point out is that the Transfers will be up to date by download the update. It will prompt you to do so when loading the game. The game is difficult to start off with even for the hardcore Pro Evoer. Everything has been overhauled on this game from passing to shooting, to tackling to defending etc. Passing will take a little time to adjust to but once you've had some practise, it'll fall into place. Passing has to be timed, directed and weighted. There is no more pressing the X button only, everything has to be directed otherwise the pass will go where your player is facing. Through balls are great, again have to be timed perfectly weighted, they look great when you pull them off. In addition to this, it'll depend on the attributes of the player, eg. Ozil & Alonso will play a better through ball than Vidic & Terry even if you use the same weight, direction etc. Hint: Practise makes perfect.
Shooting has been overhauled. One of the best changes in my opinion, it's no longer easy to just shoot and hope. Now it is all about timing, direction and perfecting the power of the shot, otherwise Row Z calls. Not even with strikers like Benzema, Rooney etc can you hit and hope. The one player where you you'll probably have the hit hope is Ronaldo. There is always one player on PES games who is favoured, not even Messi is favoured. One on ones are harder, get the ball on target 8 times out of 10 you score (goalkeepers further down). It is difficult to always get the shot on target. The only problem I have with shooting is some shots float like a feather. Looks daft to be honest. The same applies with penalties, they look pretty poor, maybe it's just me and my timing.
Tackling - One thing to Say - QUALITY. Some juicy challenges and the 50/50 tackles are great but you must time them and be in the right position.
Tactics are spot on in my opinion. You choose your strategy, formation etc. The drag and drop option is very good, simple solution. Defenders stay in position and don't drift away, midfielders command the middle of the park and strikers look for runs to exploit the opposition. The best tactic is the pressure gauge, the higher the better. It is actually the best tactic to victory too although you don't always have it easy because you'll notice through some matches that the opposition changes tactics to counter your own.
Set plays might take the longest to master, especially free kicks. You can practise free kicks on training mode forever, but come match day, it's different. I've practised with Sneijder and Ronaldo, scored some top goals, but yet to score one in a match, closest I've come is smashing the bar with Sneijder. Corners tend to be easy at times, cross, header, goal. Most of my goals have come from corners. Defending set plays is a mixture, some you win, some you lose, unpredictable adding a different dimension to the game.
Online play will depend on your internet connection, the better it is the better the flow.
There is a whole range of tournaments ie Champions League, 4 domestic leagues etc. Also you have the improved Master League which also includes the European Super Cup as well as the Champions League/Europa League etc.
Sadly comes the bad points. Goalkeepers. Year after year nothing seems to change. One on ones always get parried straight ahead rather than out wide. A rare few go wide. Simple shots straight at them at a slow pace sometimes get parried, it's really bizzare that this problem never gets sorted. The good thing is that you can't score from impossible angles. Also there occasions where the player goes through the ball missing it.
Overall PES is back. Don't believe me?? Try it yourself
