I'm fine with the blackberry, it's simple, and it works and it's not a pain to navigate menus to get where I want to go. While there's elements they could add to GM to make it a bit deeper, Goalie fatigue, and injured reserves etc. I don't really need them to reinvent the wheel for it to be fun for me. The gameplay itself is still the bread and butter.
Training mini games and rookie interaction is cool and all, but really I have limited time to game as it is. All that kind of extra fluff stuff just doesn't interests me.
