Well, if they are going to show actual gameplay then this will be the biggest day as far as football gaming goes in the last 8 years for most of us.
Personally, I could care less about the graphics. It will be nice to see the living sideline. However I will be looking at three main things..
1.
Locomotion/Footplanting/Running Animations- This should be 100% noticeable right out of the gate, and we really need a complete 180 from what we had this generation. They are touting this as a top feature of this engine, and to be quite honest, it has to be! (FOR EVERY PLAYER ON THE FIELD, NOT JUST THE BALL CARRIER)
2.
Animation Engine- This should be another that should stick out pretty quickly. I dont want to see all this herky jerky, odd looking animations on every play like we currently have this generation. It is very obvious that they have had some serious issues with their animation engine this gen. Just pick up and play EA's own NHL or FIFA, or NBA 2k and see how much more smooth the game play is. (Heck pop in Madden 05 for PS2 and that is much smoother)
3.
Player Interaction- Whether it be OL/DL or DB/WR. I want to see real player interaction like FIFA's josteling system. No more of these patty cake (suction) blocking animations, or DB morphing through WR's. We need true player interaction like just about every other sports game has.
Quite honestly, I am hoping this next-gen Madden looks nothing like this generation of Madden. For the reasons that we have all been talking about the last 8 years. I really hope this Madden team has been hard at work on this new game engine...
EDIT: If there is audio, I am also interested in CROWD ATMOSPHERE. This has been severely lacking this generation and it is something they are touting as a top feature of the new engine. They really need to bring the stadium to life and suck us into the experience. IMO, the #1 thing they can do from a presentation standpoint for immersion is make the stadium come alive, and the crowd to sound, react, and swell like a real crowd. They need to act appropriately to everything happening on the field.
