I am quite addicted to it. One feature I love, is that during gameplay you can compare your score to the global highscore list, and it constantly shows the score to beat. What I do notice, there seem to be absolutely no other players. Most games have only 100-150 scores recorded, and I am not a very good player, but I manage to get in the top 10 withing 2 or 3 practice games.
Nevertheless, very cool sim, but the flipper lag is killing.
