Quoted from JY64:
You have a Pinsider with a WOZ avatar who comes on Stern game threads and bash the games shocking
It's a little more complicated than that. I help an op with his route pins and they live at my house for anywhere from a couple weeks to months (BM'66, which is nowhere close to route-ready, so it's sequestered because, unlike Stern, he's not dumping a turd on his customers) while I get them bulletproofed to go out. So I have access to pretty much every Stern and JJP and have played them extensively at home before they go out.
BM'66 is a disaster. Period. It might someday be just okay, but it's terrible now, and in no way route-ready. There's nothing there. It might as well be the late 1980s with that pin's content and rules. AeroKISS is a modified KISS layout using (verified by the OOPS! in the system settings) the KISS code skeleton. Surprised? No KISS owner is. The software has been built up differently, but the layout is clearly KISS with only minor changes.
And not to just give Stern some lumps, Hobbit from JJP is still a beautiful mess. Earns nowhere near as well as WoZ on location and isn't super-fun to play, long-term. The OP I help sent his down the road because it wasn't earning. The problems JJP is having with a buggy Ubuntu core are the biggest threat to them moving forward. Both WoZ and Hobbit have serious Linux-based bugs (WoZ lockups, Hobbit loud popping) related to the drivers in the Ubuntu core upgrade last year that make them problematic on route. And the bugs have been there for like 8 months now with no improvement at all. Since it's a Linux problem, I would have thought they would pay a Linux OS genius to work it out for them as a contractor months ago. Nope.
There. A little bit of reality for JJP and Stern. Feel better now?
