Bhatti, the PES European Community Manager, has made a blog post on the WENB forums detailing some features that unfortunately are not going to be included in PES 2014. He's done this in an attempt to get the news to fans earlier rather than later and avoid any surprises upon the games release. The omissions are indeed surprising, but we appreciate his openness and honesty.
PES 2014 will not feature rain weather effects and will also not feature any Spanish Stadiums as opposed to PES 2013, which included every La Liga stadium. The stadium editor has also been removed.
While this news is poor, this is a time when we need to stick together as a community and show Konami our support. Hopefully changes will be made in the future.
