Its interesting, since I had the same dilemma. Before buying PES 15 I checked the current prices for PES 13 and was not sure what should I do. The main reason was as someone already mentioned all the fun stuff that was there. Stadium CREATOR, importing faces + lots of editing which I trully miss in PES 15. Even only a stadium creator in our situation right now, would be the saviour. And not just that, in PES 13 you could add various adds, ML presentation was really cool, all the player presentation when you buy it, you as a manager sitting by table and talking about club or while surfing in menus, you see your players in training ground. All these little details are so fun and makes difference. Also you had these confetti on the pitch when playing in Argentina. Surely, back then, Konami had some people in theyr team, company, that knew how to make game much more fun, that knew what people would really like and what would help to lift game to another level as far as presentation, licensing is concerned. I mean us PES fans know really well what licensing problems do to the game and invent thing like stadium creator was very helpful. They could`ve moved to the same direction, adding at least 9-10 fake leagues or adding even unlimited amount of them so all of us can create any league that we want. Now they have 3 leagues (two of them not European) and ability to use them in ML... Maybe after some years they will figure out that its not enough. Anyway, back on topic, besides all the fun stuff you could do in PES 13, there were things that stopped me buying it. And one of the main reasons was goalkeepers, who movemed really weird in PES 13. Sometimes they would jump as a thrown potato sack. Now, back then, I would`ve just enjoyed of what I have, but when I played PES 15 it really kind of changed my mind. And there were lots of other things that makes PES 13 just outdated, so despite very limited editing in PES 15, the gameplay still wins. It really reminds old good PES 5/6 days, there are some elements still missing, but with more games and some times, PES 15 really becomes some kind of revelation. There needs to be lots and lots of work to be done in future, but the basics are really good so far.
