Have you even really played PES5 and not just the demo? It is very different than PES4
gameplay wise. The graphics are the same, some faces look better but thats all. The game does not even play the same as PES4. Go read some PES forums, you can't play PES5 the way you played PES4, you have to learn a whole new game. Many people are having a problem with this. Like I said, just check out some of the forums.
I've played soccer for the past 18 years (I started when I was 4, I'm 25... minus 3 years of college) and I'll tell you, soccer hasn't changed much. As a result, gameplay shouldn't change much. The control tightness maybe, but not the style. If they've changed how you direct a kick, or how you curve a strike, fantastic... you're still kicking a ball. That's not a new challenge, it's improved control. PES5 is better than FIFA for that exact reason, which justifies its purchase, but to say Burnout is "just an expansion pack" is unfair.
