no worries MRG not shitting all over it, constructive criticism and questions welcome. Answering in order
1. It's raised for 3 reasons. Reason 1 is the doors up front, we figured it would be a cool bash target or a neat game mode start. kind of like bash the doors 3-4 times to get them open, then shoot the scoop behind it to get a certain mode started, it'd be kind of weird if there was just doors sticking up out of nowhere. Reason 2, If you look at the photos there's 2 holes cut on the main playfield beneath. I haven't designed it yet but both of those cutouts would lead to a single subway. The front cutout behind the doors would be a scoop going down, the other would just remain a cutout to be fed by that upper playfields' trap door or the pop up post under it. Having the mechs under the main playfield they would be directly in the way of that single subway and it wouldn't be possible. reason 3.... honestly I just think upper playfields are cool if they're done well, kind of like a reward/challenge for getting up there.
2. I agree with you that they should absolutely be fun. Ours has a couple of things going on. The photo doesn't do a great job showing it because I'm not done designing, but the upper playfield would have the outer orbit passing under it in the rear. There would also be a pop up post that could sometimes come up to feed the rear cut out making it so that outer orbit shot could also capture a ball. So by my count there's 4 shots total coming from the upper playfield. Rear orbit pass through, rear orbit capture, upper playfield trap door, and finally the bash doors up front. I have no idea if its fun yet or not, but that's what the foam layout and prototyping is for lol.
3. completely agree. I even said that will probably happen. if its in the center it'll probably be a ball drain every time coming back which is obnoxious lol. more than likely it'll be moved to the back left... maybe. I have multiple design files going on at the same time. This file isn't apart of my playfield master file that the CNC work is based off of, instead I just started designing in a new file to figure out how much space it would take up with the mechs included. Once the size of this playfield is mostly worked out I can make it out of foam and see where this playfield might fit best on the real playfield and make shots on it. once its in a place I'm happy with, I can make a working prototype of the upper playfield to see if it then functions the way I want it to. Iterative design is a very long process and so much ironing out.
ALL OF THAT BEING SAID. I have no idea if this'll be fun or not, Id like to imagine it would be but wont know until we get a semi functional prototype going. if its not fun after trying to iron out all of the mechanical kinks that will inevitably be there, then I'm completely alright with scrapping the idea. Above all else, this upper playfield needs to be fun.
