I have to disagree here.
Full game for me is much better than demo and please stop this nonsense about Fidel's gameplay patch for FIFA 14. Yes, it did change the game, but FIFA 15 is heaps and bounds better in every aspect than modded FIFA 14 to me (even with best gameplay patch which was shoreloosers 1.4).
Weight, interia, player individuality, ball physics, more than 4 players jumping for ball on corners, proper foot usage for players, living pitch, atmosphere on stadiums... Plus dynamic lightning, dynamic weather, etc. Better AI, better player collisions, the game is polished in so many areas (better linking animations between transitions).
Sure, there are issues, but I believe day 1 patch will be coming when the game is released in Europe on 26th.
For now, OP volleys are the only issue. The game pace is slower than in demo now too.
Played on Xbox One the other day, but the changes are substantial, making it the best FIFA to date imo. Played every single one of them since 98 and loathed 14 (as much as I did 12).
However, expecting much more from PES 2015 this year. Disappointed that EA didn't touch on Career Mode. NADA! NONE was done here! They only concentrated on FUT mode this year
. For single players it is heart breaking!
