I think I would rank this solidly among the upcoming titles to consider buying this year if it was priced like Elvira/BM66 a premium-only Stern title.
I think it looks like an awesome shooter. Ripping those spinners during the spinner mode looks fun as hell. Opto spinners for the win. Or ripping them anytime on the fly after an inlane lights a spinner is old-school, but a pinball rule I love and has been phased out in modern games or nerfed in scoring to be worthless.
I agree the quicker play, less deep (but it does med to be deep enough...) gameplay would be nice as a change vs the rest of a modern lineup. I love my GZ, but the long game times are a drag for multiplayer games hanging with friends (a new startup gametype to play "Terror of Mecha GZ" or a new similar mode vs a normal gave is coming per Keith, and will help in that dept, but I digress...).
Just some further polish on the display screens would go a long way to alleviating that complaint for me. As-is I was pretty disappointed with the screen usage in the stream though. I have to think that was placeholder stuff - surely?!
Anyway, I think this could be an amazing pin, and I'd like to have one. Unfortunately I expect I never will as I'm not willing to spend even current LE prices for any pin, period. And never will.
