Hi Juri, a lot of notable thoughts there, have you had a chance to see the public videos? Not with all of those specific control sequences but all of that is already in the development build I believe, have a look at the videos in the media section and you can see much of that content demonstrated. The idea as a purely physics driven engine is that the number of swings and angle of attack are more player controls driven than anything else.
There are no true animations as I understand it from what I have seen in the videos, it is all hinge constraint rigging straight off the physics engine. which means a simple interface which requires a massive amount of player skill. Having worked with physics controls in the past with my own projects, I can assure you it will not be boring, possibly a bit frustrating until you get used to precision control, but not boring. A very long time ago as gaming technology goes there was a game, though I forget the name of it which had a similar idea though poorly executed... a boxing game as I recall which had been made purely on collision systems rigging like a marionette technology has come a very very long way since then, as far as I know this is the only system to implement precision physics to this degree. A least in the gaming community...
Just glancing over some of the recent posts here I see a lot of things which are addressed on the main page. If I personally were to desire something of the game I would have to say a fairly sizable wardrobe, but that's just me, and likely not feasible for a small group. Modeling clothing takes time... lost of time. Well, modeling anything really...
Now, knowing how the system is purely physics driven, I wonder how complicated it would be to handle swimming, in many of the videos I have seen beautiful water areas but they never go into the water. I enjoy being able to go for a swim in games sometimes... though I have noticed several more recent games have stopped including that into the game play. Hopefully the team will have time to show us more of the current work sometime in the near future, until then, may we all dream of the magnificence of things to come.
