Well, I played one prospects' game and one BFTC. my impression so far is pretty positive!
Firstly, I was delighted at how cool the intimidation factor is. Guys that I went after hard or won in fights against would make the occasional bad pass. It wasn't overdone, it was just interesting.
Boardplay is a great addition too, and it is a bit awkward at first, but it makes it seem like a more "real" game.
Also, the goalies ARE better for sure.
Lastly, playing BFTC on Pro-Hardcore resulted in one of the most fun NHL games I can recall. In hardcore, the direction and speed of your pass is really up to you. It's so different than previously, but sending passes off the boards and stuff feels great.
Me likey!
