People that say that the gameplay is the only thing that matter and give as an example PES5/6 forget that in 2005, PES5 was probably one of the best looking sport games. What you had in other titles presentation-wise you had in PES5, from the wet pitch to breathing vapour coming from players mouth’s on a cold night. Today it looks basic, but at the time it wasn’t. The only thing that FIFA had better was the licenses.
Nowadays, you look at PES2015 - and even forgetting about the presentation off the pitch - and where are those realisms? The nets are weak. The pitch doesn't have wet spots. The hair of players doesn't move (like in PES2010 (!)). No pitch degradation. And I’m not forgetting that the faces, players’ models and kits are way better than FIFA, but the rest is way worse.
I can give a pass this year, since they need to focus all their human resources on fixing the gameplay, but next year it better be on-par with other sports title, not necessarily better, but on the same level.
