I don't find AS as fun as the other two. A fine and fun game, but not at the level of the others.
So that leaves us AC/DC and MET. And that is a really hard choice, because they are both great games. I think the question becomes simple at that point... Bash toys? If you like bash toys, MET is your game. You can play it hitting nothing but bash toys and have fun. Hit Sparky, then hit Sparky. Then hit Sparky to collect jackpots. It's fun. But the real stuff happens when you play towards Crank It Up. In CIU MET adds the perfect amount of pressure. It's hard enough to start that when you're playing it
You know a drain is more costly, and it messes with your head. The rules just keep on giving. Wonderful game.
AC/DC is the grandfather of this group, but the old guy still has a trick or two. Everyone seems to have a different strategy on AC/DC that they play. The Pro is awesome now that they got rid of the Angus face. But the game can also be brutal. It's all about risk vs reward. AC/DC is a points game. Meaning you are not on some quest, you are on it to build up and collect a massive jackpot. And then you try to get them even bigger. The mistake people make sometimes owning it is to get locked into one small feature of the game that scores well for them. That can make it one dimensional for them. They fail to realize that if they just hit start and plunge the ball on the random song that started gives you new objectives to go after.
Personally I pick AC/DC, but only a little bit over MET. Both are great games, and you would be happy with either.
