I get that, I do. Pace of play is also determined by completed pass success as well. PES AI really main attack is a string of completed passes, that has been the consistent theme in all videos, including klash's and inf0's videos that I have seen - along with dmend's.
I made a video on FIFA that you can control the pace of play by controlling one player (CM/DM) as well. That's not just a PES thing. PES has also had the issues of controlling all 11 players ever since they switched to this Fox engine. It was never like this before.
Eitherway, I'm remaining objective, there are two games that also include PES 13 and PES 11. There is a lot of defending of PES 16 demo for some reason vs remaining objective to what could be possible. There are big issues still with the game, but it is enjoyable in the moment. It definitely doesn't look like what we see IRL though, and I think if we could tighten the field up, lower the pass speed and pass accuracy - we'd get there with PES 16. I think tactics will only go so far, but then again it's just the demo - who knows what will be modified in the full release, but I'm certain the foul radius for the referee is ineffective because of how wide open the gameplay is. Tighten it up (programming, not tactics) and you'll start seeing that radius grow closer to the action, thus fouls getting called more. This was the issue with FIFA 14 (old gen), except it was paired with pass speed and FT control (sliders, duh) to get the referee to start making obvious foul calls. Yet another reason PES needs, and always will need, gameplay sliders. I've said it for 10+ years, and I'll say it for 10+ more.
