http://petrpuck.blogspot.com/ give it a whirl.... im pretty satisfied, i just finished my first season in BE a GM... i played the majority of the games, and just went through my offseason last night, ready for season 2... the player developement needs to be a bit better but thats through a patch... but overall, am i 100% satisfied? NOPE!! but, can i live with my own tweaks to the game based on others hard work? yes....
Littman isnt totally out of the loop from what i gathered in the article, but he needs to be at the helm, like before... things ran ALOOOOT smoother with him around... reaction time was great!!!
