I hate to butt in any Avengers thread, but this one seems like the hot one and varying off topic a bit anyway.
I see people posting about small differences between Avengers pro and LE. I have to say I could not tell what the differences were (besides big feature difference) but I know there is something about it. I went to a tourney in Indy this weekend and Avengers pro was by far the fastest games going (fastest meaning short ball times). There had to be something wrong with that game, but I don't know what it was. Keep in mind it was pulled out of the box for the tourney. The highest game the whole day was 12,000,000. There would maybe be a person get Hulk multiball one out of 10 games. I never saw anyone lock enough balls for Loki multiball all day. The game played like it had a brick wall halfway up the playfield. All shots to the center ramp would spin the hell out of the spinner but then stop suddenly halfway up the ramp and roll back. Clean shots to Ironman would get part way up the lane and rattle and come back down. I actually looked to see if it had a post or something obstructing the lane the way it made the ball stop and rattle on a clean shot.
I'm not a good player, but all I could do was hit Hulk. I think I had 2 Captain America shots and 2 Hawkeye shots total in my 3 games played. I have played the LE a few times and almost always got Hulk multiball and a couple of Loki multiballs. I also never felt like it was a hard game after playing the LE...I just can't figure out what was wrong with that pro.
