I had so much hope for Mario Pinball... until it came out. Maybe, just maybe, this will turn out well. But I wouldn't bet on it.
It looks kind of like the same concept with the timers and bosses. The guys who made it made Pro Pinball, which was a very good pinball game. Maybe Mario pinball was a fluke. I'm not gonna say whether the game is bad or not, because it only matters if it's fun. But the concept of using Metroid for pinball is really odd. Metroid shouldn't be made into a farce like this. It's one of the more serious games, and when a franchise character (mario, sonic, etc) is made into a pinball game, it's comical almost. But it's not even cool, like how Odama is cool. It makes you say "woah. What?" instead of just saying "what?".
