Short version: Because I'm stupid.
Medium version: Because I've watched Predator 10,000 times, rarely ever spend money on myself, am almost certainly half way dead, am queer for underdogs, think what's been revealed so far sounds really, really bad ass and was forced to watch Wizard of Oz at least five times a year growing up because the rest of my family adored it.
Long Version:
1) Integrated theme. This is HUGE for me. Almost every memorable line in Predator fits pinball events perfectly.
2) White board. It looks like a pinball machine trying really hard to be a good pinball machine, and less like a nine year old's toy box exploded under the glass after being hit by a truck full a' Vegas. Don't get me wrong, there are some really cool Stern layouts and I'd have been happy as a fat kid at ice cream camp to win that Oz raffle, but this machine looks more my style.
3) Hunt mode. If they get that right it will be, for me, as cool as the trolls in Madness. Everything has to work right, I want to hear that awesome, "FithUhmmm", sound wipe to infrared like in the film as everything goes dark and hear some ambient Predator clicks. Oh my God. So cool if done right.
4) Software. Putting your name in and tracking your stats? Earning badges for accomplishments? Displaying you and your totally dominated friends and family on screen at once so they can witness side by side your total superiority? F to the yes.
5) Upgrades / fixes on memory stick.
6) Theme.
7) Art. This hasn't been shown yet obviously, but, man, I'd love to see a new pin with some quality hand made art.
8] Demographic. This is a pin made to be played by people my age who were young men / old boys when Predator came out. It's made for EXACTLY ME. That's what I felt like when I saw this thread, "Holy shit, these guys decided to make a pinball machine for exactly me." I respect Jack, and I want that company to survive, thrive, flourish and create a new age of pinball success. However, I take him exactly at his word, he made Oz to appeal to the broadest possible demographic. My Mom, who loves pinball and Wizard of Oz and Predator, said, "Wow, Oz will be huge with the rich gay guy crowd, they'll buy it just to have and never even play it!". I am neither rich, nor gay, and I wish both demographics all the happiness in the world, but SkitB has seemingly created this pinball machine specifically for, and only for, this guy right here. Yeah, if I'm on the list there's 249 other people, but, I honestly feel like no one is a better fit for this machine than me.
9) Mature. The vast majority of the USA considers video games, board games, pinball games, foosball games, etc... as juvenile diversions. That's why a bunch of clueless assholes are always trying to ban certain genres, titles or subjects, to save little kids. But, they don't get there's a whole, large portion of the population that grew up playing games and have no interest jumping over mushrooms or collecting fruit to feed their day glow pet. I'm almost 40. Why can't video games, board games and pinball games grow up? I sure as hell did. I never swear in front of my kids, but when they're in bed or I'm away I curse like a fucking drunk sailor watching a football game he's got $1000 riding on.
10) Because I'm pretty stupid.
