Maybe we do not need more information about game engine being released by its developers, but rather more tools that would make it easier to learn game mechanics on our own. Of course, reading forum is useful, but still there is so much "noise" here ;p.
As an example of what I mean by "tools" - I would appreciate a lot if we just have more in-game stats. Things like - number of shots contested by a player X, FG% by opposing player while defended by X, data on shots distribution and so on.
It would be also great if we could easily download historical game and player data in .csv format. I don't mean single game, but all games over a given time period.
