Ok so i tried a few games of the demo.the first impression was "this is the same as PES 2015!WTF!" However...
After a few games it is apparent that the new collission system has dramatically improved the game. The way players jostle for possession, the way they get their body in front of the ball, the way they tackle and get tackled. It is brilliantly done. The ball physics have also improved quite a bit, the ball now gets whipped in with mad curve for crosses. The shooting also feels improved, with more shooting variety depending on the players positioning. Too easy perhaps to score with top rated players if theyre in space but this is realistic. A top player will put it away 9 times out of 10 under no pressure. Havent shot enough with lower rated players to comment if lower rated players have the same accuracy
Things i dont like: too many toe poke passes, some side footed animatikns look clunky, ref too lenient at times, still no att/def increase/decrease like in previous pes and like in fifa, the sliders for tactics is too basic, like last year. Presentation has remained 90% the same, they could have polished it, i also hate that in the player details screen you cannot see the players nationality.
In saying that, i reckon if omline is not laggy this will be the best pes ever. However i very much doubt this will be the case. Pes has always been laggy online from day one when pes06 came out on the xbox360. And seeing that there has been no news about the online side of things i assume itll be same old....i dun get how fifa is flawless online but pes is so laggy, how can they not fix this
In terms of playing vs AI i dont play the CPU so cannot comment on this. Im a human v human player.
