PES11 is quite possibly, one of the most unrealistic Football Sims ever.... the speed at which the ball travels.... pure ping pong play.... to describe PES11 as "realistic" should be an insult to anyone who actually bothers using his brain before uttering sheer stupidity.
For the game truly to be put in the "simulation" category, you have to exclusively focus on the BAL aspect of the game. When you play the whole team, the simulation part is already gone out the window. Because last I checked, football teams don't operate with a hive mind. For example, old submarine sims where you control every station on the boat, is not actually a simulation. Later sims where you order the AI to perform different tasks aboard the boat on the other hand, is a simulation. The PES series is not really a simulation series, and as far as I know, never claimed to be a simulation. It is a football game, and the difference between a sim and a game is usually different perspectives on importance of realism. If you look at the difference between GP4 and F1 2010 where one game claim to be a simulator and the other a game, it is quite easy to understand the difference.
BAL on the other hand can rightfully be called a football career simulator, although not a very detailed one.
So unless someone find an official commercial where konami claims that the PES franchise is a simulation, your demands for more realism should be changed to pleas for more realism.
New Star Soccer and Trequartista are football sims, where you play one player and have to approach the game as if it's you against the world, making your career until you retire, much like BAL mode in PES.
The only people who like pes 2011 are new comers who have absolutely no clue how great game pes was back on ps2 days, even John said they are trying to get the hardcore fans back, but they failed, the game is a huge failure, and people who find this game playable have no idea what a good game is supposed to be
I think the reason why you think that, is because you where several years younger when you played those games on the PS2, and you demanded less from games than you do now. I have played the PES series for a long time, and nearly every release has been better than the last one. The concern I have had though, is that the level of improvement has been rather slim on several occasions, and I have felt that both PES and FIFA have developed extremely slow compared to other computer games, even within the sports genre.
Both companies have been milking the same cow for too long, but the leap between PES 2010 and 2011 is quite good in my opinion, and I look forward to see the next version and firmly believe that we will se a truly great football game come out of this in about two years time.
