This is a really good pinball game. I have never played Metrroid so can't say much about that. But it ROCKS for pinball!
I have probably only played it for about 2 hours all together so far so good. One small complaint is that there are only the 3 tables. Perhaps I have not played it enough and more tables will open up. But each table has so many things that pop up and whatnot that it is not boring.
Another complaint is the split screen makes it hard to see the ball and the monsters sometimes. I think they did a good job of utilizing the dual screens and there's nothing to be done about it but it is a minor annoyance when the ball is sorta in between screens.
I can recommend this to anyone who enjoys a great game of pinball.
