First off. I would love a physics based engine also man. Now with what I'm about to type, I'm not trying to excuse the devs from trying to implement one, but a physics based engine is not really needed.
We didn't have a physics based engine during the PS2/XBox era but the illusion of momentum and weight was in the game. Maybe not a perfect representation but it was there. Point being, (I understand I'm not a dev) I'm going to go out on a limb and say it cant be that difficult to correct this problem.
In my opinion its all about attention to detail. Pop in Madden or NCAA 11 on PS2 and go into practice mode and really study the players and how they move. Of course you'll notice that drastic changes in direction without loss of speed just cant happen.
You'll also notice that a completely different type of model is used current gen. The current gen player model is extremely stiff and rigid, (they dont seem to have individual limbs that move independently) while the last gen models were like marionettes (they had individual limbs) and they seemed to be actually anchored down and heavy.
Madden 12 slightly improved on this, but the player models still appear to be one solid upper/lower body without the loose movement in the hip area that we had last gen.
I dont know how they did it, but last gen Madden was more like backbreaker. It was a marionette/ragdoll player model that seamlessly transitioned into mocapped animations at the proper times. Dig into it and you'll see what I'm talking about.
Watch and compare the collisions in last gen and current gen If you haven't already. Watch and compare how the avatars turn the corner on a sweep play in last gen and current gen.
Like I say, I just want to know if they're going to do something about it or not. Please stop ignoring the threads about player movement. It just seems like they're trying to take us as some nutjobs imagining ****.
If they're not going to change it just state that you're not and your reasoning behind it. Thank you.
