Not all big black guys walk the same and surely not all short white skinny guys do as well. It just doesn't work that way. It's got to do with build and many other things, nothing to do with race or ethnicity.
Well I wasn't saying their is truth to the argument that your race = your walking style. Just that different body types walk differently. Yes we all don't walk the same and two people of the same build will walk differently.... but on the whole... asians are genrally shorter in height than other areas of the world. It's all down to their genes, as well as by the environmental conditions that they have grown up in and tons of other things. But if you take that into account... just like not all big black guys walk the same. It makes no sense that Konami then use 1 single type of build to do all of their motion capping.
- Note - I don't actually know if that is true but I'm assuming it is, as other than the few times they've signed a star like Messi and done capping on him to make just him walk and move like his real life counterpart does. I've never seen videos of them recording the motions of lots of different builds and player types.
I don't think it makes a huge huge difference as we're not going from man to woman. But at the same time, if you go a bit further on. Things like footballing technique that people pick up from their surroundings, training, culture, attitude etc... are going to be different the world over. To attempt to recreate all of those styles just by using a few Japanese motion capture people seems wrong.
They should be getting groups of people from different footballing parts of the world to do their own style of capture. So they will actually be able to recreate the right sort of mannerisms. Not just a few stars but a group of players who all have the same style of play so they can create a new base group of animations for those types of players.
The typical old style English CF that Alan shearer had for example is completely different to say Fernando Torres. They both trap the ball, shoot, move and run differently. But really if you put the stats for both men so they match up. When you use Torres and Shearer (if he was in the game) they would be using the same animations and end up feeling the same.
On Pes 2009 I think when Newcastle were a licensed team - Michaels Owen's face and body type were so wrong that it never actually felt like you were playing as him. But really it should have had the right sort of feel no matter how he looked.
If they did motion capture for a range of people from different countries, they could capture the real techniques and motions that south American footballers use which you just don't see English guys doing and so on. At the moment you have the big stars looking about right but then the rest of the team will all share the same style of movements so they all have a sort of generic style to them.
When you create a player you have something like a 'player type' or 'technique type' or something option so the base animations are set to the style of football that person actually uses. I think that would mix up the animations enough to stop everyone running along with the same style giving the game that robotic feel.
