At one point I messed with it. It was ok for the most part. Then a big update I lost my credit for training which I never got fixed. I then redid some of the training so I could play again. Another large update they didn't release a patch for, so it was full download only. At over 1GB, and the fact I wasn't that into it, I just gave up on the game.
Today the full install is 2.5GB download.
