Don't spend your money on a game you can't play.
As far as the actual game goes, the basic gameplay is similar to previous versions. It appears to have a lot of depth once you get into it.... if you get the chance to actually experience it. The one time I was able to log in and play, I felt some of the interface was a little clunkier than expected. I'm sure after more time at the wheel this will get better. Who knows if I am going to be able to play again anytime soon?
Eventually they might get it figured out, but I'm afraid that when EA gets tired of supporting it because users don't continually shovel money their way, they will shut down their servers and your investment will be gone.
